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.

EFCAB10 (HGNC:34531): (EF-hand calcium binding domain 10) Predicted to enable calcium ion binding activity. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The p.Q639H variant (also known as c.1917G>C), located in coding exon 13 of the RINT1 gene, results from a G to C substitution at nucleotide position 1917. The glutamine at codon 639 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is conserved. 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. -

This sequence change replaces glutamine, which is neutral and polar, with histidine, which is basic and polar, at codon 639 of the RINT1 protein (p.Gln639His). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RINT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1782603). 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 disruptive. 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. -
