Genes affected

RRM2 (HGNC:10452): (ribonucleotide reductase regulatory subunit M2) This gene encodes one of two non-identical subunits for ribonucleotide reductase. This reductase catalyzes the formation of deoxyribonucleotides from ribonucleotides. Synthesis of the encoded protein (M2) is regulated in a cell-cycle dependent fashion. Transcription from this gene can initiate from alternative promoters, which results in two isoforms that differ in the lengths of their N-termini. Related pseudogenes have been identified on chromosomes 1 and X. [provided by RefSeq, Sep 2009]

The c.157G>T (p.A53S) alteration is located in exon 1 (coding exon 1) of the RRM2 gene. This alteration results from a G to T substitution at nucleotide position 157, causing the alanine (A) at amino acid position 53 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
