• (TAAAA)n repeat polymorphism
• SHBG gene
• Age at menopause

Objective: To assess the potential association of the pentanucleotide (TAAAA)n repeat polymorphism in the promoter of SHBG gene with the age at menopause in a Greek female population.
Study design: Cross-sectional study. Two hundred and ten postmenopausal women aged 46-63 years were enrolled. The age at the last menstrual period and anthropometric parameters were recorded in all participants. Blood sampling for genotyping of the (TAAAA)n polymorphism of SHBG gene was performed.
Main outcome measure(s): Frequency and association of the (TAAAA)(n) alleles with age at menopause.
Results: The alleles with seven and eight TAAAA repeats were associated with the age at menopause. The age at menopause was higher in carriers than in non-carriers of the (TAAAA)7 allele (50.2 +/- 13.1 years vs. 48.0 +/- 4.8 years, p = 0.026). Furthermore, the age at menopause was lower in women carrying the (TAAAA)8 allele (47.5 +/- 4.8 years) than in women not carrying this allele (48.8 +/- 4.4 years, p=0.048).
Conclusions: The (TAAAA)7 and (TAAAA)8 alleles of the SHBG (TAAAA),, polymorphism may contribute to variation in the timing of natural menopause in postmenopausal women of Northwestern Greece.
