Submissions by phenotype
Hereditary cancer-predisposing syndrome    Benign:4 
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Variant summary: The RAD50 c.2923-5dupT variant involves the insertion of a nucleotide in the intronic region. One in silico tool predicts a damaging outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. This variant was found in 2771/115606 control chromosomes (257 homozygotes) at a frequency of 0.0239693, which is approximately 383 times the estimated maximal expected allele frequency of a pathogenic RAD50 variant (0.0000625), suggesting this variant is a benign polymorphism. In addition, another clinical diagnostic laboratory classified this variant as likely benign, without evidence to independently evaluate. Taken together, this variant is classified as benign. -
