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.385C>A (p.Q129K) alteration is located in exon 2 (coding exon 1) of the PRSS23 gene. This alteration results from a C to A substitution at nucleotide position 385, causing the glutamine (Q) at amino acid position 129 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
