An imbalance between excitation and inhibition in the cerebral cortex has been suggested as a possible etiology of autism. The DLX genes encode homeodomain-containing transcription factors controlling the generation of GABAergic cortical interneurons. The DLX1 and DLX2 genes lie head-to-head in 2q32, a region associated with autism susceptibility. We(More)
The heterogeneity of autism spectrum disorders (ASDs) confounds attempts to identify causes and pathogenesis. Identifiable endophenotypes and reliable biomarkers within ASDs would help to focus molecular research and uncover genetic causes and developmental mechanisms. We used dense surface-modelling techniques to compare the facial morphology of 72 boys(More)
Autism severity is associated with child and maternal MAOA genotypes. We replicated and extended a previously reported association between autism severity and a functional polymorphism in the monoamine oxidase A (MAOA) promoter region, MAOA-uVNTR, in a sample of 119 males, aged 2-13 years, with autism spectrum disorder from simplex families. We demonstrated(More)
Marker loci in 113 members of nine unrelated multiplex families identified by a bipolar proband were tested for linkages with primary affective disorder. Linkage was excluded between the disease locus (assuming that it was a single autosomal dominant gene) and the HLA loci at a recombination fraction of 0.2, the ABO, Rh, and Lu loci at almost 0.05 and the(More)
In 3 families with the fragile-X [fra(X)] syndrome, we have identified a minimum of 4 recombinations in 9 meioses between the syndrome locus and the coagulation Factor IX gene. Two Factor IX intragenic restriction fragment length polymorphisms (RFLPs), produced with TaqI and XmnI, were used as markers. In lod score calculations, incomplete penetrance of the(More)
