This variant is denoted RAD51D c.751A>G at the cDNA level, p.Ile251Val (I251V) at the protein level, and results in the change of an Isoleucine to a Valine (ATA>GTA). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. RAD51D Ile251Val was not observed in large population cohorts (Lek 2016, The 1000 Genomes Consortium 2015, NHLBI Exome Sequencing Project). Since Isoleucine and Valine share similar properties, this is considered a conservative amino acid substitution. RAD51D Ile251Val occurs at a position where amino acids with properties similar to Isoleucine are tolerated across species and is located in the RAD51C binding domain (Miller 2004). In silico analyses predict that this variant is unlikely to alter protein structure or function. Based on currently available evidence, it is unclear whether RAD51D Ile251Val is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
