Relevance to Autism
Several studies have found genetic association between the ITGB3 gene and autism in a number of population cohorts, and a rare mutation in the ITGB3 gene has been identified in an individual with ASD (ORoak et al., 2012).
Molecular Function
The encoded protein is the integrin beta chain beta 3 that participates in cell adhesions and cell-surface mediated signalling.
