rs1800587, also known as C-889T, is a SNP in the IL-1 alpha IL1A gene.

A study of 556 adults in the Western Australian coronary heart disease (CHD) population concluded that rs1800587(T;T) homozygotes had larger waist circumference, by 1.8cm on average, compared to major allele (C;C) homozygotes. This association was even more pronounced in patients with higher levels of obesity or inflammatory markers. [PMID 18716798]

rs1800587 increases susceptibility to Intervertebral disc disease 1.31 times for (C;T) heterozygotes and 7.87 times for (T;T) homozygotes [PMID 17471097]

This SNP has also been reported to be associated with Alzheimer's disease in a few studies, but probably ruled out in even more studies, such as this one [PMID 19158434].
