BACKGROUND: Age at menarche has a strong genetic influence. We reported recently an association between the XbaI (351A
C)and PvuII (397T
C) polymorphisms of the estrogen receptor (ER)
gene with the age of menarche in Greek adolescents. In the present study, we examined whether ER
genotypes alone, or in combination with ER
genotypes, may also influence onset of menarche. METHODS: We performed genotyping for the single nucleotide polymorphisms 1730A
G and 1082G
A of the ER
gene and examined their association with the age of menarche in the same cohort of 145 Greek girls. We then looked for a possible effect of combined ER
and
genotypes on the age of menarche. RESULTS: Menarche occurred 7 months later in girls with the AA genotype of the 1730A
G polymorphism than in girls with the AG genotype (mean ± SD: 13.23 ± 1.24 versus 12.66 ± 1.26 years, respectively; P = 0.005). The 1082G
A polymorphism was not detected in any of the girls examined. A significant effect of combined ER
and
genotypes was also apparent. Menarche occurred 11 months later in girls bearing the AA/TT,AA (ER
, ER
) genotypes compared with girls with the CC/CC,AG genotype (13.30 ± 1.27 nersus 12.41 ± 1.28 years; P = 0.042). The difference remained significant after adjusting for body mass index (P = 0.034). CONCLUSION: Combined ER
and ER
polymorphisms may influence the age of menarche.
