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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2023The c.1693G>A (p.E565K) alteration is located in exon 12 (coding exon 11) of the ALKBH8 gene. This alteration results from a G to A substitution at nucleotide position 1693, causing the glutamic acid (E) at amino acid position 565 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
