If autism were truly a disease, something of detriment, why do autistic variants of genes perpetuate?
Some variants of genes involved in the immune system could have led to improved immunity, producing a sort of "hybrid vigour".
Kojima, T. et al. Association analysis between longevity in the Japanese population and polymorphic variants of genes involved in insulin and insulin-like growth factor 1 signaling pathways.
But if the elimination of disease-causing variants of genes should prove successful, there might be no holding the line against parents who wanted to enhance strength or intelligence as well.
At the same time, Dr. Scherer added, "For autism there will not be one unifying theory but perhaps for a proportion of families there are underlying common variants" of genes that together cause the disorder.
Zhang S, Chen W, Xin L, Gao Z, Hou Y, Yu X et al. Genomic variants of genes associated with three horticultural traits2 in apple revealed by genome re-sequencing.
Half the babies in each group will be randomly assigned to have all their coding DNA sequenced and screened for 1,700 variants of genes that are associated with childhood-onset diseases.
This study was undertaken to investigate the involvement of polymorphic variants of genes related to arginine metabolism in the susceptibility of clefting.
And we're working with Columbia's Institute for Genomic Medicine to search patients' DNA to identify genes either variants of genes that are associated with bone fragility or new genes that may lead to PLO.
They also hope to collaborate with cognitive scientists to see how variants of genes like SLC6A4 affect the behavior of dogs today.
This intersubject variability in cigarette-induced pathologies is partly mediated by genetic variants of genes that may participate in detoxification process, eg, cytochrome P450 (CYP), cellular susceptibility to toxins, such as p53, or disease development.
