The results for TSLP SNP rs3806933 show that compared with the C allele, the T allele in patients with ER‐positive BC and ER‐negative BC was associated with BC risk protection (OR = 0.418, CI = 0.195–0.897; p = 0.02169 in ER+ve and OR = 0.341, CI = 0.175–0.666; p = 0.0011 in ER‐ve). The gene discussed is TSLP; the disease is breast cancer.
