Mutated Gene Linked to Epilepsy and Intellectual Disabilities in Women

Researchers at Adelaide’s Women’s & Children’s Hospital and the University of Adelaide, Australia, have found that a mutant gene causes epilepsy and intellectual disabilities specific to women. As noted in Science Daily, the study links a “large family of genes known as protocadherins with a condition known as ‘epilepsy and mental retardation limited to females’ […]

Small World After All

Three and possibly four autistic children with different mothers have all been liked to the same sperm donor, “Donor X.” CNN.com interviewed one of the mothers, Gwenyth Jackaway, whose 5 1/2 year old son Dylan is autistic. Jackaway is single and had always wanted to have a child, so she contacted contacted California Cryobank, […]

Vaccines and Genes

The April 1st CNN Money.com reviews the “recent brouhaha about 9-year-old Hannah Poling,” whose family received a settlement under the federal government’s Vaccine Injury Compensation Program “based on their claim that childhood vaccinations aggravated a rare metabolic disorder in Hannah, triggering autism symptoms.” Writer David Stipp notes that, in a 2006 survey, 54% of families […]

A Personal Matter

Yesterday, a reader left a comment on the post It’s Not the Vaccines in which she noted (1) she is pregnant and (2) her husband has a “12 year old daughter from a previous marriage who has severe autism and mental retardation. When she was about 18 months old, she had the MMR and that […]

Disruptions in Contactin 4 and Autism

Disruptions in the gene contactin 4—which helps the brain make connections—can stop the gene from working properly, and prevent from the brain from making networks, according to researchers in the Journal of Medical Genetics. The leader of the study, Dr. Eli Hatchwell of Stony Brook University Medical Center in New York, suggests that these disruptions—in […]

A Question About Theories of What Causes Autism

At the lecture on genetics and autism that I heard some of last week, I asked one of the speakers this question: Even though there is more and more evidence in support of a genetic theory of autism, why does so much public opinion seems so hesitant to accept this, and so interested in environmental […]

The NYTimes misportrays the autism “debate”

Deal in an Autism Case Fuels Debate on Vaccine is the headline for an article in today’s New York Times by Gardiner Harris about the case of Hannah Poling, the 9-year-old autistic child whose “pre-existing mitochondrial disorder…. was ‘aggravated’ by her shots,” as was conceded last week by the government in the Court of Federal […]

Gender Selection and Prenatal Genetic Testing

There is no prenatal genetic test for autism; there has been speculation that, as research into the genetics of autism develops, such a test might be created. Back in June of 2006, a team of doctors at University College Hospital in London—in view of the fact that autism is diagnosed in boys at a much […]

A Rubric for Genetic Diagnosis of Autism

The previous post considered a physiological marker for autism that draws on research on the brain responses of adolescents with Asperger Syndrome playing an interactive game. Drs. G. Bradley Schafer of University of Nebraska and Nancy J. Mendelsohn of Children’s Hospitals and Clinics of Minnesota have published an article in the January issue of Genetics […]

Genetically Modified…..Babies?

A team of researchers from Newcastle University has created an embryo from three separate parents by using DNA from one man and two women. The researchers hope that, by using this technique, women with diseases of the mitocondria (”mini organelles that are found within individual cells”) do not pass on diseases such as fatal liver […]
