The results showed that rs2585428 was associated with cancer risk in Caucasian population, rs4809960 was associated with breast cancer risk in Caucasian population, and rs6022999 was associated with cancer risk in Asian population.
Adult weight gain has a higher premenopausal BC risk with double variant T alleles of rs927650 compared to women carrying at least one wild-type C allele (OR for TT = 1.82, 95% CI 1.10-3.01; for CT = 0.93, 95% CI 0.76-1.14; for CC = 1.12 95% CI 0.93-1.35).
When studies were stratified by cancer type, our results indicated that rs2585428 significantly decreased the risk of pancreas cancer, while rs4809960 significantly decreased the risk of breast cancer.
The inverse association for plasma 25(OH)D with breast cancer was more pronounced (OR 0.43, 95 % CI 0.27-0.68) among women with the common allele for CYP24A1, rs927650 (p for interaction on a multiplicative scale = 0.01).

We studied the relationships between CYP24A1 gene SNPs (rs2209314, rs2585428, rs2762941, rs3787555, rs4809959, rs73913757, rs912505, and rs927a650), adult weight change and BC risk.
Our results suggested that rs1059122 (FAM13A), rs17748 (PHLDB1), and rs4809957 (CYP24A1) might contribute to breast cancer susceptibility in the Chinese Han population.
Among CYP24A1 polymorphisms, rs6068816 was associated with a 72 % reduction in breast cancer risk (TT vs. CC, OR 0.28, 95 % CI 0.10-0.76; p trend = 0.01), but for rs13038432, the 46 % decrease included the null value (GG vs. AA, OR 0.54, 95 % CI 0.17-1.67; p trend = 0.03).

Sunlight measures were not associated with breast cancer risk, however significant interactions between time outdoors in the teen years and three unlinked genotypes were found for VDR (rs1544410, rs2228570) and CYP24A1 (rs1570669).
Two polymorphisms in CYP24A1 were associated with increased breast cancer risk (rs34043203, P(trend)=0.03; rs2762934, P(trend)=0.005) and one with reduced breast cancer risk (rs1570669, P(trend)=0.048).

The most extensively studied SNPs including rs10735810, also known as rs2228570 (Fok1, VDR), rs1544410 (Bsm1, VDR), and rs2296241 (CYP24A1), were not associated with breast cancer risk.
Of the SNPs studied, only rs12570116 in the ACADSB gene, rs4760658 in the VDR gene and rs6091822, rs8124792, and rs6097809 in the CYP24A1 gene, and rs10902845 in C10orf88 had a nominal association with breast cancer risk (P < 0.05 for all).
