Variant summary

Our verdict is Pathogenic. The variant received 10 ACMG points: 10P and 0B. PM5PP5_Very_Strong

The NM_002769.5(PRSS1):c.86A>C(p.Asn29Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N29I) has been classified as Pathogenic.

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.
