From the NIH: Autism, Genetics and Environment

BALANCE TIPS TOWARD ENVIRONMENT AS HERITABILITY EBBS IN AUTISM?
Non-inherited genetic factors also in the mix -- NIH-funded science

The largest and most rigorous twin study of its kind to date has found that shared environment influences susceptibility to autism more than previously thought.

The study, supported by the National Institutes of Health, found that shared environmental factors - experiences and exposures common to both twin individuals - accounted for 55 percent of strict autism and 58 percent of more broadly defined autism spectrum disorders (ASD) (http://www.nimh.nih.gov/health/topics/autism-spectrum-disorders-pervasive-developmental-disorders/index.shtml). Genetic heritability accounted for 37 percent of autism and 38 percent of ASD. Random environmental factors not shared among twins play a much smaller role.

Earlier twin studies had estimated the genetic heritability of autism to be as high as 90 percent, due to much lower estimates of concordance - both members of a twin pair having the disorder - in fraternal twins. The new study found such concordance to be four to five times higher.

"High fraternal twin concordance relative to identical twin concordance underscores the importance of both the environment and moderate genetic heritability in predisposing for autism," explained Joachim Hallmayer, M.D., of Stanford University, Palo Alto, Calif. a grantee of the NIH's National Institute of Mental Health. "Both types of twin pairs are more often concordant than what would be expected from the frequency of autism in the general population. However, the high concordance among individuals who share only half their genes relative to those who share all of their genes implies a bigger role for shared environmental factors."

Hallmayer, senior co-investigator Neil Risch, Ph.D., of the University of California, San Francisco, and colleagues report on findings of the California Autism Twins Study (CATS) in the July 2011 issue of the Archives of General Psychiatry.

"These new findings are in line with other recent observations supporting both environmental and genetic contributions to ASD, with the environmental factors likely prenatal and the genetic factors highly complex and sometimes not inherited (http://www.nimh.nih.gov/about/director/2011/autism-spring.shtml)," said NIMH director Thomas R. Insel, M.D.

Studies are under way to determine if autism may be traceable, in part, to environmental exposures (http://www.niehs.nih.gov/health/topics/conditions/autism/index.cfm) early during pregnancy.

The new study is the first to analyze a large sample of twins drawn from the general population; previous twin studies have been based on more limited samples, such as patients in treatment. It is also the first to employ the latest standard in diagnosing autism, which requires structured clinical assessments based on interviews with the parents as well as direct observation of the child.

Drawing upon state records, the researchers initially identified 1,156 twin pairs, with at least one member affected by an ASD, born to California mothers between 1987 and 2004. The children were all at least 4 years old, an age when autism can be reliably diagnosed. Ultimately, this group was winnowed to 192 twin pairs - 54 identical and 138 fraternal - for genetic analysis. Since autism disproportionately affects males, males outnumbered females by four to five times, with 80 of the pairs including both sexes.

Concordance for ASD was 77 percent among identical male pairs, and 31 percent among fraternal male pairs. In females, concordance for ASD was more closely spaced - 50 percent for identical and 36 percent for fraternal pairs. By contrast, previous studies had found concordance rates for fraternal twins that were much lower, ranging only in the single digits.

"Spectrum disorders traditionally thought to have less genetic loading turn out to stem from a similar mix of environmental and genetic heritability as narrowly defined autism," noted Thomas Lehner, Ph.D., chief of the NIMH Genomics Research Branch.

Yet, there can also be genetic influences that are not inherited from parents. New evidence (http://www.eurekalert.org/pub_releases/2011-06/yu-yrd060611.php) emerged last month that rare, spontaneous mutations (http://www.nimh.nih.gov/about/director/2010/in-search-of-the-missing-genetic-signals.shtml) occur at abnormally high rates in autism.

"Such non-inherited genetic changes were proposed as a major mechanism of autism susceptibility, based on the very low concordance among fraternal twins found in earlier studies and evidence of increased risk associated with older parental age," explained Risch. "In light of the high fraternal twin concordance observed in our study, such new mutations may play a more limited role, since they would primarily occur in only one member of a fraternal pair, which would not lead to concordance."

Also participating in the research were investigators at: Autism Genetic Resource Exchange; California Department of Public Health; Kaiser Permanente; University of California, Davis. The research was also funded by Autism Speaks.

Angie’s List: Listing towards the Wrong Side

Angie’s List: Listing towards the Wrong Side
An Open Letter to Angie Hicks Founder of Angie’s List


 Dear Angie, 

I knew optometry was going to be in for a rough time when I read the first sentence. In a recent Angie’s List magazine article, “Can’t See Eye to Eye”[a] (written by Michael Schroeder) the very first sentence set the tone when the author used the following quote: “Even though I love my optometrist, I would never ever let him do surgery.”

Dear, dear Angie, for an organization that prides itself on solid, truthful reviews of services and products, this article does your business and your readers a major disservice. It is obvious that the author does not understand the profession or Optometry, nor the issues involved between Optometry and ophthalmology.
As the American Optometric Association notes, Doctors of Optometry (ODs) are the primary health care professionals for the eye. Optometrists examine, diagnose, treat, and manage diseases, injuries, and disorders of the visual system, the eye, and associated structures as well as identify related systemic conditions affecting the eye. We are America’s eye doctors. We serve more people in more communities than any other eye care professional. And we do this with fiscal restraint. Optometrists are the only eye care provider in more than 3,500 communities across the United States. The bottom line is that our patients receive outstanding care at a reasonable cost.

Please note that ophthalmologists are not optometrists. They do not go to optometry school. They do not receive the well rounded education a primary care optometrist receives. They are narrow in scope and practice. 

Undergraduates, who wish to have a career in optometry, often participate in the same pre-med/pre-denistry/pre-optometry programs that all who wish a career in health care pursue. After completing their undergraduate study, they then apply to optometry school. Competition for these doctoral positions is stiff. At the Illinois College of Optometry, where I am a Professor of Pediatrics and Binocular Vision, the graduating class of 2011 had 144 members receiving diplomas and were chosen from a pool of 912 applicants. This graduating class was comprised of 67% women with representation from 26 states, 6 Canadian Provinces and several foreign countries. 

Our students take the same anatomy, physiology, pharmacology and disease courses that MDs, DOs (Doctors of Osteopathic Medicine) and other health care providers take. In fact future MDs, DOs and ODs often take these courses side by side at many schools and colleges of Optometry. Optometrists often have more hours in pharmacology than most of those individuals studying medicine.

Clinically our students work with a wide variety of patients. These patients often have hypertension, diabetes, and other serious chronic and acute systemic and ocular diseases. They often work side by side with MDs while diagnosing and treating these patients. At the Illinois Eye Institute (IEI), the clinical arm of the Illinois College of Optometry, we see almost 100,000 patient visits a year. In the Pediatrics/Binocular Vision Service, where I spend most of my time, we see up to 14,000 patient visits per year. Our patients range in age from infants to those who even seniors would consider senior. 

After examining patients at the IEI, we send our students around the world for additional experience. Our future Doctors of Optometry receive education and clinical training in China and Australia, in Dubai and all over the United States. They work alongside other health care professionals in hospitals, secondary and tertiary health care centers and even in large group practices. Optometrists and optometry students from Spain and Australia often spend several weeks at the IEI to increase their clinical skills as well.

Before graduation all students must pass vigorous state and national board written and clinical examinations. I’m proud to say that the graduates of the Illinois College of Optometry in 2010 had a NBEO Part 1 Basic Science Pass Rate of 97.16%, Part 2 Clinical Science Pass Rate of 96.5% and a Part 3 Patient Care Pass Rates of 100%! This year we also had one of our students receive the highest score on the NBEO Part 1 of all those taking the test around the country.

Although the Doctor of Optometry is a terminal degree and no additional training is required before the graduate can practice, more than 15% of the Class of 2011 went on to participate in residency programs. These programs include specialized education and clinical training in primary care, eye disease, pediatrics, binocular vision, and vision therapy, as well as, cornea and contact lens, refractive surgery, vision rehabilitation and several other areas. This advanced training is conducted at various Veterans’ Affairs Medical Centers across the country, secondary and tertiary health care centers, various schools and colleges of Optometry and other similar facilities. All of these residencies are associated with a college or school of Optometry and are accredited by one or more organizations.

Optometrists have earned the title of Doctor. 

All health care professions use education to advance their scope of practice to serve patients better and to make affordable access to care possible. Optometry is not different in this regard. I do not know of a single doctor who would use any procedure, non-medical, medical or surgical, if they were not thoroughly trained in its application. Medicine does this. Optometry does this.

Now back to your article. The author uses “scare tactics” by telling stories of optometrists who perhaps did not provide the best care. How sad that the author stopped at just telling these stories about optometrists. I have very sad stories to tell you of where ophthalmology failed their patients and their patients suffered serious visual impairment because of this. I could tell you the story about the refractive surgeon who used an old microtome blade during surgery and bits of metal chipped off this worn blade and to this day are embedded in the patient’s cornea. I could tell you about another refractive surgery mishap, where with glasses the patient saw 20/20 and unfortunately after surgery the best the patient could see was 20/40 with halos and glare.

All doctors make mistakes no matter what their training. We are human after all. And there are some doctors of any variety (MD, DO, OD, PhD, DDS) who should not be in practice. You did your readers and subscribers a major disservice by using such yellow journalism. I thought your standards were higher than this.

The author takes another dig at Optometry when he states, “…post optometry school education can amount to weekend courses at the Holiday Inn to learn surgery.” Where do you think our MD colleagues receive their post-graduate education? Yes, MDs sometimes learn new surgical procedures at the Holiday Inn as well. It is not where we learn, but how well we learn it that matters. Too bad Mr. Schroeder doesn’t realize this. Most of my colleagues receive their post graduate education during the annual meetings of such prestigious organizations as the American Academy of Optometry, the American Optometric Association, and the College of Optometrists in Vision Development. 

By the way, did you know that our OMD colleagues are so frightened by Optometry’s ability to successfully increase their scope of practice through education that they do not allow optometrists to attend their meetings! If ophthalmology really cared about their patients more than their pocket books, wouldn’t you think they would want any who treat patients to have the best education possible from as many sources as possible? Obviously, this is not true for organized ophthalmology.

And now…it’s time to educate Mr. Schroeder about our legislative system. His article comes across as if Optometry pulled some fast political maneuvers that involved hundreds of thousands of dollars. What Optometry did was to make it quite clear to the law makers that Doctors of Optometry provide excellent, accessible and affordable medical/surgical care to their patients. Ophthalmology could not counter this with any rationale argument. It’s a shame that Mr. Schroeder didn’t take the time to find out how many hundreds of thousands (millions?) of dollars MDs have available to ensure access to law makers throughout the states and nationally. This is just one more example of sloppy, incomplete and just plain bad reporting.

If Angie’s List magazine was called the National Enquirer, I could understand how such an article could be published. We expect more from you. You let us down.

One of the best ways Americans have available to us to show displeasure with a product or service is to not buy the product or use the service. Until you can restore my faith in what otherwise appears to be a solid organization, I am seriously considering canceling my subscription to Angie’s List. I am also recommending that all Optometrists, their families and our patients re-evaluate the benefits of subscribing to Angie’s List as well.

We all want Angie’s List to be an organization that provides information we can trust. You failed to do this by publishing this biased article.

Sincerely,

Dominick M. Maino, OD, MEd, FAAO, FCOVD-A
Professor, Pediatrics/Binocular Vision Illinois Eye Institute/Illinois College of Optometry

Oxytocin Promises Hope In Prader-Willi Syndrome

....Prader-Willi syndrome is a rare genetic disorder which affects one child in 25,000. Children born with this syndrome have a range of complex neurological and developmental problems which continue into adult life. These can manifest as cognitive and behavioral difficulties, weight gain, problems in controlling their temper and attendant difficulties in socialization. New research published in BioMed Central's open access journal Orphanet Journal of Rare Diseases, demonstrates that the hormone oxytocin is able to positively affect patients by improving trust, mood, and reducing disruptive behavior.....

Comments: I've had the opportunity to work with several children and adults with Prader-Willi syndrome and they have always been a pleasure to examine. Any intervention that improves the lives of those with PWS should be welcome. (See Libov A, Maino D. Prader-Willi syndrome. J Am Optom Assoc 1994;65:355-59). A genetic disorder that involves the same gene is also interesting. See

Learning Disabilities Linked to Progressive Aphasia

CHICAGO, Jan. 11 -- Learning disabilities may be a precursor of later language loss in patients with primary progressive aphasia. Learning disorders were more common among such patients and their family members than among healthy controls or those with other dementias. However, the researchers cautioned, the findings do not suggest that all patients with dyslexia are at elevated risk of the neurodegenerative condition.
Action Points
Explain to interested patients that this study suggests that learning disabilities may be a risk factor for primary progressive aphasia.
Caution that the study does not suggest that all patients with learning disabilities are at risk for neurodegenerative disease.
"This relationship may exist in only a small subgroup of persons with dyslexia," they wrote.
Primary progressive aphasia is characterized by the progressive loss of language functioning over time with relative preservation of other cognitive domains within the first 2 years of symptom onset. Neuroanatomically, the pathological changes are frequently asymmetric and most severe in the hemisphere dominant for language, usually the left.
As a follow-up to observations of learning disabilities among a small set of patients, the researchers studied prevalence of self-reported learning disabilities among participants in the Northwestern Alzheimer's Disease Center registry.
The analysis included 699 individuals in the registry who responded to questions about learning disabilities.
Among the participants, 108 met criteria for primary progressive aphasia, 154 had typical amnestic Alzheimer's disease, and 84 had the behavioral variant of frontotemporal dementia. These clinical diagnoses were made by consensus of a neurologist and a neuropsychologist at the single center.
Patients with primary progressive aphasia were significantly more likely than those with Alzheimer's disease, the behavioral variant of frontotemporal dementia, or healthy controls to have a personal history of learning disability (14.8% versus 4.5%, 7.1%, and 1.4%, respectively, P0.001 for all).
First-degree family members (parents, siblings, and children) of patients with primary progressive aphasia also had a significantly higher prevalence of learning disabilities compared with the other participants (29.6% versus 10.4% of those with Alzheimer's, 14.3% of those with the variant of frontotemporal dementia, and 6.8% of healthy controls, P0.001 for all).
Based on their initial results, the researchers also retrospectively reviewed medical records of the 23 primary progressive aphasia patients who reported personal or family history of learning disabilities.
They found "unusual familial concentrations of learning disabilities in these families," especially dyslexia.
In three families, nearly all of the children of the primary progressive aphasia patients were reported to have language-specific learning disabilities.
In one case, the primary progressive aphasia patient did not learn to read until about age 10, always had poor spelling, and was unable to learn a foreign language despite attempts to do so. All three of his children and both of his granddaughters were reported to have dyslexia. Only one of his sons was able to graduate from high school.
In another case, all three of the primary progressive aphasia patient's children had learning disabilities related to speech, reading, spelling, writing, arithmetic, and learning language.
In the third case, the patient struggled with English, literature, and spelling, and received speech therapy early in life despite doing well in math and science. Of the patient's four children, two sons and a daughter were reported to have difficulty with spelling and one of the sons also had difficulty with reading.
All five siblings of another primary progressive aphasia patient were reported to have persistent difficulty with reading and spelling.
"These results suggest that learning disabilities may constitute a risk factor for primary progressive aphasia," the researchers said, "providing additional clues concerning the selective vulnerability in this syndrome."
Learning disabilities in these patients, they said, may be a marker for pre-existing developmental or acquired susceptibilities in language areas of the brain that are neurologically compensated but eventually become a focal point for degenerative disease that would have struck elsewhere if they had different susceptibilities.
Since the association was found for both personal and family history of learning disabilities, this risk factor may have "a genetic component that is developmentally expressed as dyslexia in some individuals and as a neurodegenerative disease, also affecting language, in others."
The findings may underestimate the frequency of learning disabilities in these patients because family and even personal history in this complex are likely to be incomplete, the researchers noted.
"In our clinical practice," they wrote, "we encounter many patients with primary progressive aphasia who report that spelling was never their 'strong suit' or that they could not learn new languages, but who would not have identified themselves as having a learning disorder."
The study was supported by the National Institute on Aging, the Alzheimer's Disease Core Center, and the National Institute on Deafness and Other Communication Disorders.
The researchers reported no conflicts of interest.
