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]

Likely pathogenic, criteria provided, single submitter	clinical testing	3billion	Oct 02, 2021	Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic supporitng evidence (ClinVar ID: VCV000006764.1, PMID: 20516114, PS1_P). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.00001061, PM2). The variant was observed in trans with a pathogenic variant (NM_001211.5: c.1045del) as compound heterozygous (3billion dataset, PM3). Patient's phenotype is considered compatible with Mosaic Variegated Aneuploidy Syndrome 1 (3billion dataset, PP4). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -
Pathogenic, no assertion criteria provided	literature only	OMIM	Nov 01, 2004	- -
Pathogenic, criteria provided, single submitter	clinical testing	Invitae	May 14, 2022	This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 814 of the BUB1B protein (p.Arg814His). This variant is present in population databases (rs28989182, gnomAD 0.01%). This missense change has been observed in individual(s) with mosaic variegated aneuploidy (PMID: 15475955, 20516114, 30512160). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 6764). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). Experimental studies have shown that this missense change affects BUB1B function (PMID: 20516114). For these reasons, this variant has been classified as Pathogenic. -
