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 was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.06635514).
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000046 (7/152210) while in subpopulation SAS AF = 0.000414 (2/4828). AF 95% confidence interval is 0.0000729. There are 0 homozygotes in GnomAd4. There are 7 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Autoimmune lymphoproliferative syndrome, type III caused by mutation in PRKCD Uncertain:1
Aug 22, 2022
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 661 of the PRKCD protein (p.Ala661Thr). This variant is present in population databases (rs149202171, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with PRKCD-related conditions. ClinVar contains an entry for this variant (Variation ID: 541625). 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. In 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. -
