Summary MD‐1 (myeloid differentiation 1; also known as Ly86, lymphocyte antigen 86), interacting with RP105, plays an important role in Toll‐like receptor 4 (TLR4) signalling pathway. It has been suggested to be involved in the pathological mechanism of inflammation and atopic diseases. The purpose of this study was to investigate the genetic association between single nucleotide polymorphisms (SNPs) of MD‐1 promoter and coding region and mite‐sensitive allergy in Taiwanese children. We conducted a case‐control study on 237 controls and 281 allergic patients sensitive to Dermatophagoides pteronyssinus (Der p) and Dermatophagoides farinae (Der f) by genotyping 35 SNPs in MD‐1 gene region. In the promoter region we identified three SNPs, rs1334710, rs4959389, and rs977785 that are associated with mite‐sensitive allergy in Taiwanese children. The P ‐values ranged from 0.0150 to 0.009. The haplotypes including promoter region were also associated with mite‐sensitive allergy. Our results suggested that MD‐1 could be a susceptible gene for mite‐sensitive allergy in Taiwanese children.
