Relevance to Autism

Rare variants and genetic association have been found with the GRIP1 gene and autism in AGRE and SCAP cohorts (Mejias et al., 2011). In particular, that study showed convincing higher incidence of missense variants in 480 cases compared to 480 controls. Although segregation within pedigrees was not perfect, the variants were shown to be functional due to altered binding to glutamate receptor 2/3.

Molecular Function

The encoded scaffold protein mediates trafficking and membrane organization of various transmembrane proteins.

Strong Candidate

See all Category 2 Genes

We 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.
