ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 5 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.053030305 fraction of the gene. Cryptic splice site detected, with MaxEntScore 3.4, offset of 4, new splice context is: tacGTaatt. 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;

PP5

Variant 2-37090723-G-T is Pathogenic according to our data. Variant chr2-37090723-G-T is described in ClinVar as [Pathogenic]. Clinvar id is 3062155.Status of the report is no_assertion_criteria_provided, 0 stars.
