Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_007173.6(PRSS23):c.128A>C(p.Gln43Pro) variant causes a missense change. The variant allele was found at a frequency of 0.0000197 in 152,110 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q43H) has been classified as Uncertain significance.

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]

Collection Method:clinical testing

The c.128A>C (p.Q43P) alteration is located in exon 2 (coding exon 1) of the PRSS23 gene. This alteration results from a A to C substitution at nucleotide position 128, causing the glutamine (Q) at amino acid position 43 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
