ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.012874044 fraction of the gene. Cryptic splice site detected, with MaxEntScore 5.1, offset of 0 (no position change), new splice context is: aatatataatttttttttAGcag. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
