Genes affected

PRSS55 (HGNC:30824): (serine protease 55) This gene encodes a member of a group of membrane-anchored chymotrypsin (S1)-like serine proteases. The enocoded protein is primarily expressed in the Leydig and Sertoli cells of the testis and may be involved in male fertility. Alternate splicing results in multiple transcript variants.

PRSS51 (HGNC:37321): (serine protease 51) 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]

The c.157T>C (p.C53R) alteration is located in exon 2 (coding exon 2) of the PRSS55 gene. This alteration results from a T to C substitution at nucleotide position 157, causing the cysteine (C) at amino acid position 53 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
