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]
TH2LCRR (HGNC:40495): (T helper type 2 locus control region associated RNA)

ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 17 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 2.7, offset of -8, new splice context is: ctgGTatct.

Submissions by phenotype

Hereditary cancer-predisposing syndrome Pathogenic:2
Likely pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2022The c.3612_3618+5del12 variant results from a deletion of 12 nucleotides at the splice junction boundary of coding exon 23 and intron 23 of the RAD50 gene. The deleted nucleotide region is well conserved in available vertebrate species. Alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay. As such, this alteration is classified as likely pathogenic. -
Likely pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 12, 2023This variant results in the deletion of part of exon 23 (c.3612_3618+5del) of the RAD50 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in RAD50 are known to be pathogenic (PMID: 19409520). This variant is present in population databases (no rsID available, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with RAD50-related conditions. ClinVar contains an entry for this variant (Variation ID: 408396). Studies have shown that this variant is associated with altered splicing resulting in multiple RNA products (Invitae). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
