Description
This variant is denoted RAD51C c.671A>G at the cDNA level, p.Tyr224Cys (Y224C) at the protein level, and results in the change of a Tyrosine to a Cysteine (TAT>TGT). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. RAD51C Tyr224Cys was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Since Tyrosine and Cysteine differ in polarity, charge, size or other properties, this is considered a non-conservative amino acid substitution. RAD51C Tyr224Cys occurs at a position that is moderately conserved across species and is not located in a known functional domain. In silico analyses are inconsistent regarding the effect this variant may have on protein structure and function. Based on currently available information, it is unclear whether RAD51C Tyr224Cys is pathogenic or benign. We consider it to be a variant of uncertain significance.
