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.

Ambry Genetics

Aug 05, 2024

The c.303G>C (p.W101C) alteration is located in exon 2 (coding exon 2) of the PRSS55 gene. This alteration results from a G to C substitution at nucleotide position 303, causing the tryptophan (W) at amino acid position 101 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
