-Relevance to Autism
Nominal association of common variants in the STX1A gene with ASD (in particular high-functioning autism and Asperger syndrome) has been reported in several publications (Nakamura et al., 2008; Nakamura et al., 2011; Durdiakova et al., 2014).
Molecular Function
This gene encodes a member of the syntaxin superfamily. Syntaxins are nervous system-specific proteins implicated in the docking of synaptic vesicles with the presynaptic plasma membrane. This gene product is a key molecule in ion channel regulation and synaptic exocytosis.

Strong Candidate
Nominal association of common variants in the STX1A gene with ASD (in particular high-functioning autism and Asperger syndrome) has been reported in several publications (Nakamura et al., 2008; Nakamura et al., 2011; Durdiakova et al., 2014). A paternally-inherited missense variant that was shown experimentally to decreases STX1 phosphorylation and reverse transport of dopamine without decreasing dopamine uptake was iidentified in a male ASD proband from the Simons Simplex Collection in Cartier et al., 2015; this variant was not observed in an unaffected female sibling. Exon-disrupting deletions affecting the STX1 gene were also observed in 83 Japanese ASD cases but not in 51 Japanese controls (Kofuji et al., 2017).
