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]

May 26, 2024

The c.585C>A (p.D195E) alteration is located in exon 5 (coding exon 5) of the ALKBH1 gene. This alteration results from a C to A substitution at nucleotide position 585, causing the aspartic acid (D) at amino acid position 195 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
