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

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.82).
BP6
Variant 11-88312569-G-A is Benign according to our data. Variant chr11-88312569-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 258190.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00526 (801/152240) while in subpopulation NFE AF = 0.00854 (581/68030). AF 95% confidence interval is 0.00797. There are 3 homozygotes in GnomAd4. There are 386 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 3 Unknown,AR gene
