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 BUB1B c.1001C>T (p.Pro334Leu) missense change has a maximum subpopulation frequency of 0.13% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/variant/15-40477786-C-T). In silico tools are not in agreement about the effect of this variant on protein function, but to our knowledge these predictions have not been confirmed by functional assays. This variant has been reported in a patient with Ph+ acute lymphoblastic leukemia (PMID: 26580448). It has also been identified in 2/1358 non-cancer control individuals in a study of individuals with multiple primary cancers (PMID: 29641532). To our knowledge, this variant has not been reported in individuals with mosaic variegated aneuploidy syndrome. In summary, this variant meets criteria to be classified as of uncertain significance based on the ACMG/AMP criteria: no criteria met. -
