Association between the serotonin 1A receptor C（-1019）G polymorphism and major depressive disorder in the northern Han ethnic group in China

Background Recent studies have suggested that susceptibility to major depressive disorder （MDD） might be related to the serotonin 1A receptor （5-HTR1A） C（-1019）G polymorphism. In this study, we aimed to assess the association between 5-HTR1A C（-1019）G polymorphism and MDD in the Northern Han ethnic group of China.
Methods The C（-1019）G of 5-HTR1A was detected with polymerase chain reaction （PCR） in 400 patients with MDD and 400 unrelated age- and sex-matched healthy control subjects. Association between the C（-1019）G and MDD was statistically analyzed.
Results There was a statistically significant difference between MDD patients and controls in both the genotype distribution （X^2=10.913, df=2, ,P=0.004） and the allele frequency （X^2=10.379, df=1, P=0.001 ）, and a significant difference in the genotype distribution and the allele frequency was found both in the female subjects （Genotype distribution： X^2=15.406, df=2, P=0.000; allele frequency： X^2=15.552, df=1, P=0.000） and the late-onset subjects （Genotype distribution X^2=7.771, df=2, P=0.021 ; allele frequency： X^2=8.007, df=1, P=0.005） in the two groups.
Conclusion These results suggest that 5-HTR1A C（-1019）G polymorphism is probably associated with MDD and it is likely to be the susceptible gene locus for the female and late-onset MDD.

Association between estrogen receptor β gene Rsa1 polymorphism and depressive disorder in peri-menopausal and menopausal women

Objective: To investigate estrogen receptor β (ERβ) gene Rsa1 polymorphism and concentration of estrogen, FSH and LH in serum in peri-menopausal and menopausal women with depressive disorder. Methods: Seventy-four peri-menopausal and menopausal women with depressive disorder met ICD-10 and CCMD-3 assessment criteria for depressive disorder were recruited. ERβ gene Rsa1 polymorphism was analyzed with PCR-RFLP. Serum levels of estrogen, FSH and LH were measured by magnetism-ELISA. Results: The respective frequency of ERβ gene Rsa1 polymorphism was no significant difference between women with depressive disorder and the healthy women (χ2=1.106,P>0.05). The serum level of estrogen was lower in women with depressive disorder than in the healthy women (P<0.05). No difference was found for FSH and LH between two groups. Conclusion: ERβ gene Rsa1 polymorphism may be not associated with depressive disorder in the peri-menopausal and menopausal women. The serum level of estrogen is associated with depressive disorder in the peri-menopausal and menopausal women.
