-Relevance to Autism
This gene was originally identified as an ASD candidate gene based on its enrichment in an autism-associated protein interaction module. Sequencing of post-mortem brain tissue from 25 ASD cases resulted in the identification of significant non-synonymous variants in this gene with an expected false-positive rate at 0.1, confirming the involvement of this module with autism; this finding was further validated by exome sequencing of an independent cohort of 505 ASD cases and 491 controls (Li et al., 2014).
Molecular Function
This gene encodes a multi-domain scaffolding protein that is required for normal development. This protein may have a role in septate junction formation, signal transduction, cell proliferation, synaptogenesis and lymphocyte activation.

Strong Candidate


This gene was originally identified as an ASD candidate gene based on its enrichment in an autism-associated protein interaction module. Sequencing of post-mortem brain tissue from 25 ASD cases resulted in the identification of significant non-synonymous variants in this gene with an expected false-positive rate at 0.1, confirming the involvement of this module with autism; this finding was further validated by exome sequencing of an independent cohort of 505 ASD cases and 491 controls (Li et al., 2014). Missense variants in the DLG1 gene have been identified in a cohort consisting of patients with ASD or schizophrenia (Xing et al., 2016). A de novo nonsense variant in DLG1 was identified as a mosaic mutation with an allele frequency of 4% in an ASD proband from the Simons Simplex Collection in Krupp et al., 2017.

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.
