FGFR2 is a breast cancer susceptibility gene in Jewish and Arab Israeli populations.

ABSTRACT: Genetic variation in FGFR2 is a newly described risk factor for breast cancer. We estimated the relative risk and contribution of FGFR2 polymorphisms to breast cancer risk in diverse ethnic groups within Jewish and other Middle Eastern populations. We genotyped four FGFR2 single nucleotide polymorphisms (SNP) and tested for association of these SNPs and haplotypes with breast cancer risk in a population-based case-control study of 1,529 women with breast cancer and 1,528 controls. We found significant associations between breast cancer risk and all four studied SNPs in FGFR2 (P trend for all SNPs < 0.0001). In ethnicity-specific analysis, all four SNPs were significantly associated with breast cancer risk in Ashkenazi and Sephardi Jews, with a similar but not significant trend in Arabs. Haplotype analysis identified five common haplotypes (>1%). The previously described AAGT risk haplotype was significantly associated with breast cancer risk in Ashkenazi [odds ratio (OR), 1.25; 95% confidence interval (95% CI), 1.07-1.45; P = 0.0059] and Sephardi Jews (OR, 1.46; 95% CI, 1.17-1.80; P = 0.0006) compared with the reference GGAC haplotype. The AAAC haplotype was significantly associated with breast cancer risk in Sephardi Jews (OR, 1.97; 95% CI, 1.16-3.35; P = 0.0125) but not in Ashkenazi Jews (OR, 0.83; 95% CI, 0.41-1.62; P = 0.5613) or in Arabs (OR, 1.31; 95% CI, 0.80-2.14; P = 0.2881). Genetic variation in FGFR2, identified by rs1219648, may account for a substantial fraction of breast cancer in Arab (12%), Ashkenazi (15%), and Sephardi Jewish (22%) populations. The identification of population-specific risk haplotypes in FGFR2 is likely to help identify causal variants for breast cancer.

Project description:BACKGROUND:Social support is generally perceived to facilitate health in postpartum women; however, previous research shows that this is not always true. Social interactions intended to provide support can be perceived as negative and in turn, may have negative impacts on maternal health. The purpose of the present study was to asses if social support and negative interactions at one month after childbirth can predict maternal health four months after childbirth, and if this relationship is influenced by culture. METHODS:This prospective longitudinal cohort study included randomly selected Arab (n?=?203) and Jewish (n?=?202) women who attended Mother and Child Health Clinics in Northern Israel one month after giving birth. The women were interviewed at one and four months after childbirth using a questionnaire including measures of health (self-reported health (SRH) and health problems), socioeconomic and demographic status, obstetric characteristics, social support, negative social interactions and perceptions of customs and traditions intended to help the mother cope after childbirth. Multivariable regressions were run to identify the variables predicting health four months after childbirth. RESULTS:The response rate for both interviews was 90%. Negative social interactions one month after childbirth significantly predicted health problems in Arab and Jewish women (Beta 0.20 and 0.37 respectively) and SRH among Arab women only (odds ratio (OR) 0.32, confidence interval (CI) 0.19-0.54) four months after childbirth. Social support at one month after childbirth significantly predicted better SRH in both Jewish and Arab women four months after childbirth (OR 2.33, CI 1.38-3.93 and 1.59, CI 1.01-2.46 respectively) and fewer health problems only among Jewish women (Beta -?0.37). CONCLUSIONS:Social support and negative social interactions appear to be predictive of health in postpartum women. Associations varied between Arabs and Jews, indicating that social support may be more important for predicting health among Jewish women and negative interactions may be more important among Arab women. Healthcare practitioners should be aware of the cultural context and social circumstances of postpartum women to ensure they receive the social support and care they need.
