Genes affected

PRKCD (HGNC:9399): (protein kinase C delta) The protein encoded by this gene is a member of the protein kinase C family of serine- and threonine-specific protein kinases. The encoded protein is activated by diacylglycerol and is both a tumor suppressor and a positive regulator of cell cycle progression. Also, this protein can positively or negatively regulate apoptosis. Defects in this gene are a cause of autoimmune lymphoproliferative syndrome. [provided by RefSeq, Aug 2017]

The p.Asn348Ser variant (rs33911937) has not been reported in the medical literature or gene specific variation databases. This variant is listed in the NHLBI GO Exome Sequencing Project with an overall population frequency of 0.10 percent (identified on 13 out of 13,006 chromosomes) and is listed in the Exome Aggregation Consortium Browser with an overall population frequency of 0.089 percent (identified on 108 out of 121,348 chromosomes). The asparagine at position 348 is highly conserved, up to Frog (considering 15 species) (Alamut v2.9.0) but is also serine in Elephant suggesting this change may be evolutionarily tolerated. Computational analyses of the effects of the p.Asn348Ser variant on protein structure and function provide conflicting results (SIFT: tolerated, MutationTaster: disease causing, PolyPhen-2: benign). Altogether, there is not enough evidence to classify the p.Asn348Ser variant with certainty. -
