Relevance to Autism

SNPs have been identified in the GNAS gene in a screening of autistic, OCD and ADHD patients (Kim et al., 2000). In addition, a rare mutation in the GNAS gene has been identified in an individual with ASD (Sanders et al., 2012).

Molecular Function

The encoded protein has GTPase activity.

Support
De novo mutations revealed by whole-exome sequencing are strongly associated with autism.
ASD
Highly Cited
An imprinted transcript, antisense to Nesp, adds complexity to the cluster of imprinted genes at the mouse Gnas locus.
Recent Recommendation
Autosomal-dominant pseudohypoparathyroidism type Ib is caused by different microdeletions within or upstream of the GNAS locus.
