According to a study concerning variants in TSLP and its receptors, a significant association was observed between five TSLP single-nucleotide polymorphisms (SNPs) and AD, among which three is found in European American populations (rs1898671, rs11466749, and rs2416259) and two is found in African American populations (rs10043985 and rs2289276). This evidence concerns the gene TSLP and Alzheimer disease.
