Genes affected
SPINT2 (HGNC:11247): (serine peptidase inhibitor, Kunitz type 2) This gene encodes a transmembrane protein with two extracellular Kunitz domains that inhibits a variety of serine proteases. The protein inhibits HGF activator which prevents the formation of active hepatocyte growth factor. This gene is a putative tumor suppressor, and mutations in this gene result in congenital sodium diarrhea. Multiple transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.21343873 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 19-38290282-T-A is Pathogenic according to our data. Variant chr19-38290282-T-A is described in ClinVar as [Pathogenic]. Clinvar id is 5207.Status of the report is no_assertion_criteria_provided, 0 stars.
