Although microcephaly is a prominent feature of MVA carrying the BUB1B mutation, how BubR1 deficiency disturbs neural progenitor proliferation and neuronal output and leads to microcephaly is unknown.

Germline mutations in BUB1B, encoding BUBR1, one of the crucial components of the spindle assembly checkpoint (SAC), have been shown to cause variable phenotypes, including the recessive mosaic variegated aneuploidy (MVA) syndrome, which predisposes to cancer.

Analysis published human data revealed that human recurrent pregnancy loss (RPL) embryos and rare infant patients carrying BubR1 mutations that have been described so far have the PSCS and MVA as in BubR1 deficient/insufficient mice.

Germline mutations in the budding uninhibited by benzimidazoles 1 homolog beta gene encoding BUBR1 cause premature chromatid separation (mosaic variegated aneuploidy) [PCS (MVA)] syndrome, which is characterized by constitutional aneuploidy and a high risk of childhood cancer.

Combined analysis of patient cells and functional protein replacement shows that all MVA mutations fall in two distinct classes: those that impose specific defects in checkpoint activity or microtubule attachment and those that lower BUBR1 protein abundance.

Biallelic and heterozygous mutations of the BUB1B gene have been reported in mosaic variegated aneuploidy (MVA), a rare disorder characterized by constitutional mosaic aneuploidies associated to severe intrauterine growth retardation, microcephaly and, in most cases, to premature chromatid separation (PCS), highlighting the key role of human BUBR1 in chromosome segregation.
