Furthermore, this chromosome region includes three other genes related to autism: the calcium channel, voltage-dependent, alpha 1 F (CACNA1F) associated with syndromic autism and schizophrenia44, the phosphatase 1, regulatory (inhibitor) subunit 3 F (PPP1R3F) from which rare mutations have been found in autism45 and histone deacetylase 6 (HDAC6) from which a partial skipping of exon 3 was found in a subject with ASD46. The gene discussed is CACNA1F; the disease is autism.
