Description

Variant summary: The RAD50 c.1174_1177delCAGA (p.Gln392LeufsX8) variant results in a premature termination codon, predicted to cause a truncated or absent RAD50 protein due to nonsense mediated decay, which are commonly known mechanisms for disease. One in silico tool predicts a damaging outcome for this variant. This variant is absent in 245944 control chromosomes. In addition, one clinical diagnostic laboratory/reputable database classified this variant as pathogenic. The variant of interest has not, to our knowledge, been reported in affected individuals via publications nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as likely pathogenic.
