Han et al. in a genome-wide analysis of 88,486 patients with asthma and 447,859 healthy donors using data from UK Biobank and the Trans-National Asthma Genetic Consortium15, identified several human loci among asthmatic patients and bioinformatically showed variants of candidate causal genes, such as CD200R1 that could potentially be associated with asthma immunopathogenesis. Here, CD200R1 is linked to asthma.
