Results from the analysis confirmed previous findings of some copy number variants already associated with autism, but they also found a host of other genes (SHANK2, SYNGAP1, DLGAP2 and the X chromosome — linked DDX53 - PTCHD1 locus) in which mutations seem to be linked to autism.
After collecting information from school counselors about any social difficulties experienced by the girls, Skuse's group found that 40 % with the maternal X chromosome were likely to have problems at school, versus only 16 % of girls with the paternal X. «It seemed to us there could only be a genetic explanation for that,» Skuse says, because he says there were no other differences between the two sets of girls.

Research from other scientists at Johns Hopkins, he says, had suggested that some tumors, particularly those that affect the nervous system, have mutations in the ATRX gene, which produces proteins that appear to maintain the length of telomeres, repetitive segments of DNA on the ends of chromosomes that typically shorten each time a cell divides.
They found that in each case, even though individual cells had gained or lost the same chromosome, they behaved very differently from each other.
Chromosomes come in two matching sets, one from each parent, but the first human genome sequences published in 2001 (one by Venter, the other by federally funded researchers) were pastiches of both sets from several different individuals.

Other medical sequencing projects will use DNA sequencing to: discover new genes that are involved in common diseases; identify the genes responsible for dozens of relatively rare, single - gene (autosomal Mendelian) diseases; sequence all of the genes on the X chromosome from affected individuals to identify those involved in sex - linked diseases; and survey the range of variants in genes known to contribute to certain common diseases.
Professor Baron - Cohen commented: «Although these very clear sex differences in brain structure may reflect an environmental or social factor, from other studies we know that biological influences are also important, including prenatal sex steroid hormones (such as fetal testosterone) as well as sex chromosome effects.
Unlike animals, in plants the addition of two complete sets of chromosomes from different species often leads to the creation of a new species — for example cereal wheat — that is a fertile and successful hybrid organism despite the radical genetic stress that this generates (Kashkush and others 2002, Kashkush and others 2003).
