Genes affected

BUB1 (HGNC:1148): (BUB1 mitotic checkpoint serine/threonine kinase) This gene encodes a serine/threonine-protein kinase that play a central role in mitosis. The encoded protein functions in part by phosphorylating members of the mitotic checkpoint complex and activating the spindle checkpoint. This protein also plays a role in inhibiting the activation of the anaphase promoting complex/cyclosome. This protein may also function in the DNA damage response. Mutations in this gene have been associated with aneuploidy and several forms of cancer. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

The p.K1081M variant (also known as c.3242A>T), located in coding exon 25 of the BUB1 gene, results from an A to T substitution at nucleotide position 3242. The lysine at codon 1081 is replaced by methionine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
