• chr5-34908937-G-C
• rs1763743665
• NM_002853.4:c.677C>G

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_002853.4(RAD1):​c.677C>G​(p.Ser226Cys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S226F) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: RAD1 NM_002853.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 9.44
• Publications: 0 publications found

Genes affected

RAD1 (HGNC:9806): (RAD1 checkpoint DNA exonuclease) This gene encodes a component of a heterotrimeric cell cycle checkpoint complex, known as the 9-1-1 complex, that is activated to stop cell cycle progression in response to DNA damage or incomplete DNA replication. The 9-1-1 complex is recruited by RAD17 to affected sites where it may attract specialized DNA polymerases and other DNA repair effectors. Alternatively spliced transcript variants of this gene have been described. [provided by RefSeq, Jan 2009]

TTC23L (HGNC:26355): (tetratricopeptide repeat domain 23 like) Predicted to be located in cytoplasm; microtubule cytoskeleton; and midbody. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
