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.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PM1
In a disulfide_bond (size 130) in uniprot entity TRY1_HUMAN there are 13 pathogenic changes around while only 2 benign (87%) in NM_002769.5
BP4
Computational evidence support a benign effect (MetaRNN=0.012422681).
BP6
Variant 7-142751983-C-T is Benign according to our data. Variant chr7-142751983-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 459184.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=3, Uncertain_significance=1, Benign=1}.
BS2
High AC in GnomAd4 at 43 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
