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 Likely_pathogenic. Variant got 6 ACMG points.

• PVS1: Splicing variant, NOT destroyed by nmd, known LOF gene, truncates exone, which is 0.07566204 fraction of the gene. Cryptic splice site detected, with MaxEntScore 6.4, offset of 0 (no position change), new splice context is: gaaGTaaga. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP3: Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.

This sequence change falls in intron 13 of the RINT1 gene. It does not directly change the encoded amino acid sequence of the RINT1 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs761799563, gnomAD 0.02%). 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: 410784). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
