Eloranta et al. (2008) added to this body of work by looking at two single nucleotide polymorphisms of Vitamin D Binding protein (DBP) and found the DBP 420 variant Lys was less frequent in IBD cases compared with controls (allele frequencies, p = 0.034; homozygous carrier genotype frequencies, p = 0.006). The gene discussed is DBP; the disease is inflammatory bowel disease.
