Genes affected

RRM1 (HGNC:10451): (ribonucleotide reductase catalytic subunit M1) This gene encodes the large and catalytic subunit of ribonucleotide reductase, an enzyme essential for the conversion of ribonucleotides into deoxyribonucleotides. A pool of available deoxyribonucleotides is important for DNA replication during S phase of the cell cycle as well as multiple DNA repair processes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]

The c.1747G>T (p.V583F) alteration is located in exon 15 (coding exon 15) of the RRM1 gene. This alteration results from a G to T substitution at nucleotide position 1747, causing the valine (V) at amino acid position 583 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
