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.

Computational evidence support a benign effect (BayesDel_noAF=-0.86).

BP6

Variant 7-142752857-C-T is Benign according to our data. Variant chr7-142752857-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 258800.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr7-142752857-C-T is described in Lovd as [Benign]. Variant chr7-142752857-C-T is described in Lovd as [Benign].

BS1

Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.00264 (3864/1461332) while in subpopulation MID AF= 0.0339 (195/5758). AF 95% confidence interval is 0.03. There are 36 homozygotes in gnomad4_exome. There are 2326 alleles in male gnomad4_exome subpopulation. Median coverage is 47. This position pass quality control queck.

BS2

High AC in GnomAd4 at 314 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Ambry Genetics

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
