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]

Collection Method: clinical testing

The c.3124G>C (p.E1042Q) alteration is located in exon 23 (coding exon 23) of the CADPS2 gene. This alteration results from a G to C substitution at nucleotide position 3124, causing the glutamic acid (E) at amino acid position 1042 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
