Genes affected
CADPS (HGNC:1426): (calcium dependent secretion activator) This gene encodes a novel neural/endocrine-specific cytosolic and peripheral membrane protein required for the Ca2+-regulated exocytosis of secretory vesicles. The protein acts at a stage in exocytosis that follows ATP-dependent priming, which involves the essential synthesis of phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2). Alternative splicing has been observed at this locus and three variants, encoding distinct isoforms, are described. [provided by RefSeq, Aug 2008]

CADPS-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesMar 21, 2023The CADPS c.3780A>G variant is not predicted to result in an amino acid change (p.=). Based on available splicing prediction programs (Alamut Visual Plus v1.6.1) this variant is predicted to create a cryptic splice acceptor site nearby the canonical splice acceptor site on exon 29 (NM_003716.3); however, to date this prediction has not been proven by functional studies. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
