Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PS3

The NM_001211.6(BUB1B):c.2441G>A(p.Arg814His) variant causes a missense change. The variant allele was found at a frequency of 0.000018 in 1,612,728 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). ClinVar reports functional evidence for this variant: "SCV000762862: Experimental studies have shown that this missense change affects BUB1B function (PMID:20516114).". Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R814C) has been classified as Uncertain significance.

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]
