▶Smoking, the xenobiotic pathway, and clubfootAssociationN=1,776Sommer A. et al.(2011)· Birth Defects Research Part A: Clinical and Molecular Teratology
This family-based association study examined genetic variation in xenobiotic metabolism genes and clubfoot risk. In 1,776 individuals from 619 families, rs1048943/CYP1A1 showed significant altered transmission (p=0.003), and CYP1A2 variants demonstrated both maternal (rs11854147, p=0.03, RR=1.24) and fetal (rs2470890, p=0.01, RR=1.33) genotypic effects. A significant gene interaction was detected between rs105740/EPHX1 and rs1799929/NAT2 (p=0.007). The authors conclude that xenobiotic metabolism genes may contribute to clubfoot susceptibility, particularly in the context of maternal smoking exposure.
▶Polymorphisms in genes of the steroid receptor superfamily modify postmenopausal breast cancer risk associated with menopausal hormone therapyAssociationN=218S. Abbas et al.(2010)· International Journal of Cancer
This candidate gene association study examined 218 postmenopausal women at high breast cancer risk, testing 79 SNPs in steroid metabolism, receptor, cell cycle control, DNA repair, and carcinogen metabolism genes for associations with abnormal breast tissue cytomorphology (RPFNA atypia) as a biomarker for HRT-related breast cancer risk. Key findings: RAD54 Gln929Glu (rs3088074, OR=1.74), TFR Gly142Ser (rs3817672, OR=1.98, p=0.0025), VEGF 3'UTR (rs3025039, OR=2.12), and ACE I/D (rs4646994, OR=0.55) were associated with RPFNA atypia. RAD23B Ala249Val (rs1805329) showed strongest association with worsening cytomorphology on HRT versus off HRT (p=0.0009) and ERCC1 3'UTR (rs3212986) was borderline significant (p=0.0015). Results suggest DNA repair gene polymorphisms may modify breast tissue response to exogenous estrogens.
About CYP1B1
This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. The enzyme encoded by this gene localizes to the endoplasmic reticulum and metabolizes procarcinogens such as polycyclic aromatic hydrocarbons and 17beta-estradiol. Mutations in this gene have been associated with primary congenital glaucoma; therefore it is thought that the enzyme also metabolizes a signaling molecule involved in eye development, possibly a steroid.
