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]

Ambry Genetics

Jul 31, 2023

The c.1321G>A (p.V441I) alteration is located in exon 13 (coding exon 13) of the RRM1 gene. This alteration results from a G to A substitution at nucleotide position 1321, causing the valine (V) at amino acid position 441 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
