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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PRKCD. . Gene score misZ 3.1145 (greater than the threshold 3.09). Trascript score misZ 3.8606 (greater than threshold 3.09). GenCC has associacion of gene with common variable immunodeficiency, autoimmune lymphoproliferative syndrome, type III caused by mutation in PRKCD, autoimmune lymphoproliferative syndrome, autosomal systemic lupus erythematosus type 16.
BP4
Computational evidence support a benign effect (MetaRNN=0.13371032).

Autoimmune lymphoproliferative syndrome, type III caused by mutation in PRKCD Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 23, 2018In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This sequence change replaces alanine with threonine at codon 8 of the PRKCD protein (p.Ala8Thr). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and threonine. This variant is present in population databases (rs368029897, ExAC 0.002%). This variant has not been reported in the literature in individuals with PRKCD-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. -
