}}SNPs in the [[IL31]] gene have been associated with nonatopic [[eczema]]. Three haplotypes comprised 94% of the haplotypes identified in a German group of patients, defined as follows:

Haplotype A: [[rs6489188(G)]] and [[rs11608363(A)]]

Haplotype B: [[rs6489188(A)]] and [[rs11608363(G)]]

Haplotype C: [[rs6489188(G)]] and [[rs11608363(G)]]

Individuals homozygous for haplotype A were strongly associated with nonatopic [[eczema]] compared to individuals not carrying that haplotype. {{PMID|17900679}}
