Genes affected
ALKBH8 (HGNC:25189): (alkB homolog 8, tRNA methyltransferase) Enables tRNA (uracil) methyltransferase activity; tRNA binding activity; and zinc ion binding activity. Involved in cellular response to DNA damage stimulus; tRNA methylation; and tRNA wobble uridine modification. Located in cytosol and nuclear body. Implicated in autosomal recessive non-syndromic intellectual disability. [provided by Alliance of Genome Resources, Apr 2022]
