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]

Oct 22, 2021

The c.394G>A (p.D132N) alteration is located in exon 3 (coding exon 3) of the ALKBH1 gene. This alteration results from a G to A substitution at nucleotide position 394, causing the aspartic acid (D) at amino acid position 132 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
