Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 4P and 5B. PS3BP4_StrongBS2_Supporting

The NM_002769.5(PRSS1):​c.623G>C​(p.Gly208Ala) variant causes a missense change. The variant allele was found at a frequency of 0.000219 in 1,614,144 control chromosomes in the GnomAD database, including 3 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). ClinVar reports functional evidence for this variant: "SCV001187149: "In one functional study, this alteration retained normal trypsin activity" and additional evidence is available in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G208R) has been classified as Uncertain significance.

Genes affected
PRSS1 (HGNC:9475): (serine protease 1) This gene encodes a trypsinogen, which is a member of the trypsin family of serine proteases. This enzyme is secreted by the pancreas and cleaved to its active form in the small intestine. It is active on peptide linkages involving the carboxyl group of lysine or arginine. Mutations in this gene are associated with hereditary pancreatitis. This gene and several other trypsinogen genes are localized to the T cell receptor beta locus on chromosome 7.

PRSS1 Gene-Disease associations (from GenCC):
  • hereditary chronic pancreatitis

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PS3
PS3 evidence extracted from ClinVar submissions: SCV001187149: "In one functional study, this alteration retained normal trypsin activity; however, it also resulted in reduced trypsinogen secretion (Schnür A et al. Gut, 2014 Feb;63:337-43),"
BP4
Computational evidence support a benign effect (MetaRNN=0.020391077).
BS2
High AC in GnomAd4 at 53 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
