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]

The CADPS c.3477+2T>G variant is predicted to disrupt the GT donor site and interfere with normal splicing. This variant is predicted to disrupt a canonical splice donor site according to an in silico splicing algorithm (SpliceAI, Jaganathan K, et al. 2019. PubMed ID: 30661751). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.033% of alleles in individuals of African descent in gnomAD. Only a few splice variants have been reported in CADPS with a potential association with disease phenotypes (see, for example, Table 2, Shaheen et al. 2016. PubMed ID: 26633546; Table 1, Bruel et al. 2019. PubMed ID: 31231135; no reports in ClinVar). While we suspect this variant could be pathogenic, at this time the clinical significance of this variant is interpreted as uncertain due to the absence of conclusive functional and genetic evidence. -
