-Relevance to Autism
Two de novo missense variants in the SASH1 gene were identified in ASD probands from the Simons Simplex Collection (Iossifov et al., 2014); one of these variants was later determined to be a postzygotic mosaic mutation (PZM) in Lim et al., 2017. A second non-synonymous PZM in this gene was identified in an ASD proband in Lim et al., 2017; comparison with a background set of 84,448 privately inherited variants demonstrated that this gene harbored more PZMs than expected based on background rates (2/571 observed vs. 10/84,448 expected; hypergeometric P-value of 2.0E-03).
Molecular Function
This gene encodes a scaffold protein involved in the TLR4 signaling pathway that may stimulate cytokine production and endothelial cell migration in response to invading pathogens. The encoded protein has also been described as a potential tumor suppressor.

criteria met
See SFARI Gene'scoring criteriaWe considered a rigorous statistical comparison between cases and controls, yielding genome-wide statistical significance, with independent replication, to be the strongest possible evidence for a gene. These criteria were relaxed slightly for category 2.
