Genes affected

ENSG00000255439 (HGNC:):

PRSS53 (HGNC:34407): (serine protease 53) Predicted to enable serine-type endopeptidase activity. Predicted to be involved in proteolysis. Predicted to be located in extracellular region. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0152 (2319/152124) while in subpopulation AFR AF = 0.0486 (2016/41482). AF 95% confidence interval is 0.0468. There are 60 homozygotes in GnomAd4. There are 1089 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 60 gene
