Genes affected

BUB1B (HGNC:1149): (BUB1 mitotic checkpoint serine/threonine kinase B) This gene encodes a kinase involved in spindle checkpoint function. The protein has been localized to the kinetochore and plays a role in the inhibition of the anaphase-promoting complex/cyclosome (APC/C), delaying the onset of anaphase and ensuring proper chromosome segregation. Impaired spindle checkpoint function has been found in many forms of cancer. [provided by RefSeq, Jul 2008]

The p.Q461P variant (also known as c.1382A>C), located in coding exon 10 of the BUB1B gene, results from an A to C substitution at nucleotide position 1382. The glutamine at codon 461 is replaced by proline, an amino acid with 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. -

ClinVar contains an entry for this variant (Variation ID: 403743). This sequence change replaces glutamine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 461 of the BUB1B protein (p.Gln461Pro). This variant is present in population databases (rs747886467, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with BUB1B-related conditions. 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. 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. -
