ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 10 ACMG points.
PVS1
?
Splicing variant, NOT destroyed by nmd, known LOF gene, truncates exone, which is 0.19866666 fraction of the gene. Cryptic splice site detected, with MaxEntScore 6.8, offset of -43, new splice context is: acaccctccccctgcttcAGccc. 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
