More children with Down’s Syndrome are being born in the UK, according to today’s Times Online.
Widespread screening was introduced in 1989, and led to a steady fall in new instances of Down’s syndrome. From 717 babies born with Down’s that year, the total decreased each year, to 594 in 2000.
During the next six years the birth rate for children with Down’s rose by 15 per cent, reaching 749 in 2006, the most recent year for which figures are available from the National Down Syndrome Cytogenetic Register.
It’s noted that, while most women who receive a prenatal diagnosis of Down’s Syndrome choose …read more

Researchers from the Seaver and NY Autism Center of Excellence at New York’s Mount Sinai School of Medicine have developed a new method to detect copy number variants associated with autism spectrum disorders and have also found new chromosomal duplications that can be linked to autism.The study is published in the October 16th BMC Medical Genomics.
279 child with ASDs were screened for micro-duplications and -deletions in regions of the genome that have been connected to other cognitive conditions. The researchers detected several previously known duplications associated with autism, but also some that had not previously been recognized. The approach …read more

Having considered prenatal genetic testing and autism, what about the possible influence of the environment of the womb on a developing baby? An October 10th article in Slate with the provocative title of Womb Raider asks if future health problems occur during gestation:
Recently, a study of 1,044 mother-child pairs found that 3-year-olds born to mothers who gained too much weight during pregnancy had increased odds of becoming overweight. Somehow, it seemed, these women metabolically programmed their kids to get fat.
The Slate article immediately acknowledges the dangers of this particular line of thinking about children’s health:
The notion that children’s futures are …read more

Currently, there’s no prenatal genetic test for autism. Long ago (as in “around the time I first started writing this blog”) I referred to such testing as “fighting word“: While some would welcome the notion of knowing that a child-to-be would have a disability, others have been quick to point out the possibility of people choosing to abort a fetus if a disability were detected.
In the October 13th Babble, an online web community for a “new generation of parents,” Karen Dempsey writes about Choosing (a) Life: They said our baby would have Down’s; we said we understood. We had no …read more
