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 0.125969 fraction of the gene. Cryptic splice site detected, with MaxEntScore 1.9, offset of 12, new splice context is: tggGTcaga. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 12-6907446-G-A is Pathogenic according to our data. Variant chr12-6907446-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 3237374.Status of the report is no_assertion_criteria_provided, 0 stars.
