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]

ACMG classification

Our verdict: Pathogenic. The variant received 16 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 6, offset of 4, new splice context is: tacGTaagg. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
• PS3: PS3 evidence extracted from ClinVar submissions: SCV005834220: Studies have shown that disruption of this splice site alters PRKCD gene expression (PMID: 34264265).
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 3-53186696-G-A is Pathogenic according to our data. Variant chr3-53186696-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 89076.Status of the report is criteria_provided_single_submitter, 1 stars.
