ACMG classification
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 6 ACMG points.
PVS1
?
Splicing variant, NOT destroyed by nmd, known LOF gene, truncates exone, which is 0.11335578 fraction of the gene. Cryptic splice site detected, with MaxEntScore 11, offset of 3, new splice context is: tgtgttgtctttcatcgcAGgta. Cryptic site results in inframe 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;
