Genes affected

ALKBH5 (HGNC:25996): (alkB homolog 5, RNA demethylase) Enables mRNA N6-methyladenosine dioxygenase activity. Involved in RNA metabolic process; mRNA export from nucleus; and response to hypoxia. Located in Golgi apparatus; cytosol; and nuclear speck. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000266677 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.67).
• BP7: Synonymous conserved (PhyloP=-1.53 with no splicing effect.
• BS2: High AC in GnomAdExome4 at 5 AD gene.
