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]

This sequence change creates a premature translational stop signal (p.Arg770*) in the BUB1B gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in BUB1B are known to be pathogenic (PMID: 15475955, 21190457). This variant is present in population databases (rs750364303, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with BUB1B-related conditions. ClinVar contains an entry for this variant (Variation ID: 403749). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
