We previously investigated a small amount of SNPs in CTNNB1 gene and SFRP1 gene in a small sample of Western Chinese, and we identified that two SNPs (CTNNB1 rs4135385 and SFRP1 rs7832767) were associated with TB risk, indicating a potential role of these variants in susceptibility to TB20. This evidence concerns the gene CTNNB1 and tuberculosis.
