Case-control study of 501 young stroke patients and 1,211 controls examining 58 polymorphisms in 17 genes involved in methionine metabolism. Multiple logistic regression identified four independent risk factors for early-onset ischaemic stroke: rs10037045 BHMT (OR 1.38, p=0.033), rs682985 BHMT2 (OR 1.46, p=0.017), rs1051319 CBS (OR 3.75, p<0.0001), and rs202680 FOLH1 (OR 3.00, p<0.0001). Haplotype analyses identified significant associations with BHMT, CBS, FOLH1, MTR, PON2, TCN2 and TYMS haplotypes and stroke risk.

About TCN2

This gene encodes a member of the vitamin B12-binding protein family. This family of proteins, alternatively referred to as R binders, is expressed in various tissues and secretions. This plasma protein binds cobalamin and mediates the transport of cobalamin into cells. This protein and other mammalian cobalamin-binding proteins, such as transcobalamin I and gastric intrisic factor, may have evolved by duplication of a common ancestral gene. Alternative splicing results in multiple transcript variants.[provided by RefSeq, May 2010]
