GeneDx RCV000731878 SCV000149872 uncertain significance not provided 2014-02-24 criteria provided, single submitter clinical testing RAD50 has been only recently described in association with cancer predisposition and the risks are not well understood. This variant is denoted RAD50 c.671G>A at the cDNA level, p.Arg224His (R224H) at the protein level, and results in the change of an Arginine to a Histidine (CGT>CAT). Tommiska et al. (2006) observed RAD50 Arg224His in one individual with a personal and family history of breast cancer (1/481) and concluded that although it may affect RAD50 function, RAD50 Arg224His is rare, which limits any potential contribution to breast cancer susceptibility even if pathogenic. This variant has also been reported in two case control studies as unknown significance and not associated with breast cancer risk due to a similar frequency in cases and controls (Heikkinen 2003, Heikkinen 2006). RAD50 Arg224His was observed with an allele frequency of 0.1% (8/8600) in European Americans in the NHLBI Exome Sequencing Project. This variant is a conservative substitution of one positive polar amino acid for another, altering a position that is well conserved throughout evolution and is located in the coiled coil domain (Hopfner 2001). Multiple in silico algorithms predict that this variant may be damaging to protein structure and function. On a molecular level, the impact of this missense variant on protein structure and function is not known and thus we consider this to be a variant of uncertain significance. Furthermore, based on the currently available information, cancer risks associated with this variant, and the RAD50 gene, remain unclear.
