Genes affected
ALKBH1 (HGNC:17911): (alkB homolog 1, histone H2A dioxygenase) This gene encodes a homolog to the E. coli alkB gene product. The E. coli alkB protein is part of the adaptive response mechanism of DNA alkylation damage repair. It is involved in damage reversal by oxidative demethylation of 1-methyladenine and 3-methylcytosine. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2022The c.1075G>A (p.E359K) alteration is located in exon 6 (coding exon 6) of the ALKBH1 gene. This alteration results from a G to A substitution at nucleotide position 1075, causing the glutamic acid (E) at amino acid position 359 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
