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]

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• BS2: High AC in GnomAdExome4 at 10 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1238G>A (p.R413Q) alteration is located in exon 12 (coding exon 12) of the RRM1 gene. This alteration results from a G to A substitution at nucleotide position 1238, causing the arginine (R) at amino acid position 413 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
