16p13.3Associated Disorders
DD/NDD, ADHD, EP, EPS, ASDRelevance to Autism
Rare mutations in the CACNA1H gene have been identified with autism. In one study, missense mutations in CACNA1H were found in 6 of 461 individuals with ASD (Splawski et al., 2006).
Molecular Function
This gene encodes a T-type member of the alpha-1 subunit family, a protein in the voltage-dependent calcium channel complex. Calcium channels mediate the influx of calcium ions into the cell upon membrane polarization.
