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]

RRM1 Gene-Disease associations (from GenCC):

• progressive external ophthalmoplegia with mitochondrial dna deletions, autosomal recessive 6

  Inheritance: AR, AD Classification: MODERATE, LIMITED Submitted by: PanelApp Australia, G2P
• progressive external ophthalmoplegia with mitochondrial DNA deletions

  Inheritance: AD, AR Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

Our verdict: Likely_benign. The variant received -1 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.31081963).
