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.

The p.R256P variant (also known as c.767G>C), located in coding exon 6 of the RINT1 gene, results from a G to C substitution at nucleotide position 767. The arginine at codon 256 is replaced by proline, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 843043). This variant has not been reported in the literature in individuals affected with RINT1-related conditions. This variant is present in population databases (rs199512216, gnomAD 0.02%), including at least one homozygous and/or hemizygous individual. This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 256 of the RINT1 protein (p.Arg256Pro).
