Genes affected
ALKBH3 (HGNC:30141): (alkB homolog 3, alpha-ketoglutarate dependent dioxygenase) The Escherichia coli AlkB protein protects against the cytotoxicity of methylating agents by repair of the specific DNA lesions generated in single-stranded DNA. ALKBH2 (MIM 610602) and ALKBH3 are E. coli AlkB homologs that catalyze the removal of 1-methyladenine and 3-methylcytosine (Duncan et al., 2002 [PubMed 12486230]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2022The c.400G>T (p.A134S) alteration is located in exon 7 (coding exon 6) of the ALKBH3 gene. This alteration results from a G to T substitution at nucleotide position 400, causing the alanine (A) at amino acid position 134 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
