抄録
内容記述 STUDY QUESTION: Are the single nucleotide polymorphisms (SNPs) rs2075230, rs6259 and rs727428 at the sex hormone-binding globulin (SHBG) locus, which were identified by genome-wide association studies (GWASs) for testosterone levels, associated with testosterone levels in Japanese men?
SUMMARY ANSWER: The SNP rs2075230, but not rs6259 and rs727428, is significantly associated with testosterone levels in Japanese men.
WHAT IS ALREADY KNOWN: Previous GWASs have revealed that rs2075230 is associated with serum testosterone levels in 3495 Chinese men and rs6259 and rs727428 are associated with serum testosterone levels in 3225 men of European ancestry.
STUDY DESIGN, SIZE, AND DURATION: This is an independent validation study of 1687 Japanese men (901 in Cohort 1 and 786 in Cohort 2).
PARTICIPANTS/MATERIALS, SETTING AND METHOD: Cohort 1 (20.7 ± 1.7 years old, mean ± SD) and Cohort 2 (31.2 ± 4.8 years) included samples obtained from university students and partners of pregnant women, respectively. The three SNPs were genotyped using either TaqMan probes or restriction fragment length polymorphism PCR. Blood samples were drawn from the cubital vein of the study participants in the morning, and total testosterone and SHBG levels were measured using a time-resolved immunofluorometric assay. Association between each SNP and testosterone levels was evaluated by meta-analysis of the two Japanese male cohorts.
MAIN RESULTS AND THE ROLE OF CHANCE: The age of the two cohorts was significantly different (P < 0.0001). We found that rs2075230 was significantly associated with serum testosterone levels (βSTD = 0.15, P = 7.2 × 10−6); however, rs6259 and rs727428 were not (βSTD = 0.17, P = 0.071; βSTD = 0.082, P = 0.017, respectively), after adjusting for multiple testing in a combined analysis of two Japanese male cohorts. Moreover, rs2075230, rs6259 and rs727428 were significantly associated with high SHBG levels (βSTD = 0.22, P = 3.4 × 10−12; βSTD = 0.23, P = 6.5 × 10−6 and βSTD = 0.21, P = 3.4 × 10−10, respectively).
LARGE SCALE DATA: Not applicable.
LIMITATIONS, REASONS FOR CAUTION: This study had differences in the age and background parameters of participants compared to those observed in previous GWASs. In addition, the average age of participants in the two cohorts in our study also differed from one another. Therefore, the average testosterone levels, which decrease with age, between studies or the two cohorts were different.
WIDER IMPLICATIONS OF THE FINDINGS: The three SNPs have a considerable effect on SHBG levels and hence may indirectly affect testosterone levels.
STUDY FUNDING/COMPETING INTERESTS: This study was supported partly by the Ministry of Health and Welfare of Japan (1013201) (to T.I.), Grant-in-Aids for Scientific Research (C) (26462461) (to Y.S.) and (23510242) (to A.Ta.) from the Japan Society for the Promotion of Science, the European Union (BMH4-CT96-0314) (to T.I.) and the Takeda Science Foundation (to A.Ta.). There are no conflicts of interest to declare.
