Genes affected

CTSC (HGNC:2528): (cathepsin C) This gene encodes a member of the peptidase C1 family and lysosomal cysteine proteinase that appears to be a central coordinator for activation of many serine proteinases in cells of the immune system. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate heavy and light chains that form a disulfide-linked dimer. A portion of the propeptide acts as an intramolecular chaperone for the folding and stabilization of the mature enzyme. This enzyme requires chloride ions for activity and can degrade glucagon. Defects in the encoded protein have been shown to be a cause of Papillon-Lefevre syndrome, an autosomal recessive disorder characterized by palmoplantar keratosis and periodontitis.

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0222 (2808/126404) while in subpopulation AFR AF= 0.0422 (1297/30714). AF 95% confidence interval is 0.0403. There are 85 homozygotes in gnomad4. There are 1279 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 85 AR gene
