Four single-nucleotide polymorphisms in the human BUB1 gene.
Four single-nucleotide polymorphisms have been found in the human BUB1 gene, which encodes a kinase involved in the mitotic spindle checkpoint. A cytosine-to-thymine change in exon 10, corresponding to codon 375 (c.1124C>T), causes an amino acid substitution of serine to phenylalanine. A guanine/cytosine polymorphism in exon 4 (c.279G>C) and a thymine/cytosine polymorphism in exon 12 (c.1293T>C) do not cause amino acid substitution. The other polymorphism, of thymine/cytosine (IVS9-8T>C), is found at 8bp upstream of exon 10. As mutations of the hBUB1 gene were reported in a subset of human cancers, these polymorphisms could provide useful tools for the genetic study of susceptibility to various human cancers.
