Genes affected

RINT1 (HGNC:21876): (RAD50 interactor 1) This gene encodes a protein first identified for its ability to interact with the RAD50 double strand break repair protein, with the resulting interaction implicated in the regulation of cell cycle progression and telomere length. The encoded protein may also play a role in trafficking of cellular cargo from the endosome to the trans-Golgi network. Mutations in this gene may be associated with breast cancer in human patients.

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant has not been reported in the literature in individuals affected with RINT1-related conditions. For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1373997). This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change creates a premature translational stop signal (p.Arg256*) in the RINT1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RINT1 are known to be pathogenic (PMID: 31204009).

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.R256* variant (also known as c.766C>T), located in coding exon 6 of the RINT1 gene, results from a C to T substitution at nucleotide position 766. This changes the amino acid from an arginine to a stop codon within coding exon 6. This alteration is expected to result in premature protein truncation or nonsense-mediated mRNA decay. However, the evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear.
