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.

Collection Method: clinical testing

The c.-2A>C variant is located in the 5' untranslated region (5’ UTR) of the RINT1 gene. This variant results from an A to C substitution 2 bases upstream from the first translated codon. This nucleotide position is not well conserved in available vertebrate species. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear. -
