Genes affected

RAD50 (HGNC:9816): (RAD50 double strand break repair protein) The protein encoded by this gene is highly similar to Saccharomyces cerevisiae Rad50, a protein involved in DNA double-strand break repair. This protein forms a complex with MRE11 and NBS1. The protein complex binds to DNA and displays numerous enzymatic activities that are required for nonhomologous joining of DNA ends. This protein, cooperating with its partners, is important for DNA double-strand break repair, cell cycle checkpoint activation, telomere maintenance, and meiotic recombination. Knockout studies of the mouse homolog suggest this gene is essential for cell growth and viability. Mutations in this gene are the cause of Nijmegen breakage syndrome-like disorder.[provided by RefSeq, Apr 2010]

ACMG classification

Verdict is Benign. Variant got -19 ACMG points.

Likely benign, criteria provided, single submitter	clinical testing	Eurofins Ntd Llc (ga)	Mar 30, 2018	- -
Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Jan 08, 2018	Variant summary: The RAD50 c.2670G>A (p.Gln890Gln) variant involves the alteration of a non-conserved nucleotide causing a synonymous change and 4/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may alter ESE binding. However, these predictions have yet to be confirmed by functional studies. This variant was found in 176/277102 control chromosomes, predominantly observed in the African subpopulation at a frequency of 0.006285 (151/24026). This frequency is about 101 times the estimated maximal expected allele frequency of a pathogenic RAD50 variant (0.0000625), suggesting this is likely a benign polymorphism found primarily in the populations of African origin. In addition, multiple clinical diagnostic laboratories classified this variant as benign/likely benign. 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 benign. -
Benign, criteria provided, single submitter	clinical testing	GeneDx	Jan 23, 2014	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Nov 29, 2014	This alteration is classified as 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. -
