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 9 ACMG points.
PVS1
?
Splicing variant, NOT destroyed by nmd, known LOF gene, truncates exone, which is 0.07773386 fraction of the gene. Cryptic splice site detected, with MaxEntScore 3.3, offset of 4, new splice context is: cagGTtctt. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
PM2
?
Very rare variant in population databases, with high coverage;
PP3
?
BayesDel_addAF computational evidence supports a deleterious effect, 0.607
PP5
?
Variant 19-38287937-T-C is Pathogenic according to our data. Variant chr19-38287937-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 5206.Status of the report is no_assertion_criteria_provided, 0 stars.
