Genes affected
PRSS23 (HGNC:14370): (serine protease 23) This gene encodes a conserved member of the trypsin family of serine proteases. Mouse studies found a decrease of mRNA levels of this gene after ovulation was induced. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

The c.374G>A (p.R125Q) alteration is located in exon 2 (coding exon 1) of the PRSS23 gene. This alteration results from a G to A substitution at nucleotide position 374, causing the arginine (R) at amino acid position 125 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
