In some other cases, we found that these are gene–phenotype relationships reported as susceptibility factors with no associated HPO phenotypes available, e.g. {Asthma, susceptibility to, 1} (OMIM:607277) and PTGDR, for which the IMPC mouse orthologue Ptgdr shows decreased basophil cell number and decreased circulating alanine transaminase level. This evidence concerns the gene PTGDR and asthma.
