• Consequence: ANKRD36 NM_001354587.1 splice_acceptor, intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.0630

Genes affected

ANKRD36 (HGNC:24079): (ankyrin repeat domain 36)

ACMG classification

Verdict is Uncertain_significance. Variant got 4 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 8, offset of 0 (no position change), new splice context is: aattttttttttttttttAGcag. 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
