Genes affected

CADPS2 (HGNC:16018): (calcium dependent secretion activator 2) This gene encodes a member of the calcium-dependent activator of secretion (CAPS) protein family, which are calcium binding proteins that regulate the exocytosis of synaptic and dense-core vesicles in neurons and neuroendocrine cells. Mutations in this gene may contribute to autism susceptibility. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2009]

The CADPS2 c.3256G>A variant is predicted to result in the amino acid substitution p.Val1086Ile. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.021% of alleles in individuals of Latino descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
