BACKGROUND Fat mass and obesity-associated gene (FTO) has been associated with obesity, especially the common variant rs9939609. Polycystic ovary syndrome (PCOS) is a complex endocrine-metabolic disorder and over 50% of patients are overweight/obese. Thus FTO is a potential candidate gene for PCOS but their relationship is confusing and remains to be(More)
BACKGROUND Polycystic ovary syndrome (PCOS) is a complex endocrine-metabolic disorder. A previous genome-wide association study (GWAS) identified five single nucleotide polymorphisms (SNPs) which were independently associated with PCOS in Han Chinese. To overcome population stratification, a family-based analysis was conducted to validate whether these five(More)
OBJECTIVE To describe a case with repeated total fertilization failure due to oocyte defect. DESIGN Case report. SETTING University hospital. PATIENT(S) A patient with repeated total fertilization failure. INTERVENTION(S) Assisted oocyte activation, intracytoplasmic sperm injection (ICSI) with calcium ionophore oocyte activation, donor semen, and(More)
PROBLEM An association of polymorphism -1154G/A (rs1570360) in vascular endothelial growth factor (VEGF) gene with idiopathic recurrent spontaneous abortion (RSA) has been found in Caucasians. The aim of this study was to examine the association of VEGF -1154 with RSA in a well-defined group of Chinese Han patients. METHOD OF STUDY The VEGF -1154G/A(More)
BACKGROUND Polycystic ovary syndrome (PCOS) is a complex multifactor disorder and genetic factors have been implicated in its pathogenesis. Our previous genome-wide association study (GWAS) had identified allele frequencies in several single nucleotide polymorphisms (SNPs) in gene USP34 (Ubiquitin-Specific Protease 34) were significantly different between(More)
A previous genome-wide association study (GWAS) of polycystic ovary syndrome (PCOS) identified several susceptibility loci, with P-values about 10⁻⁵. In the present study, an independent cohort was used for a replication study to evaluate the association of RAD54B and GREB1 with polycystic ovary syndrome (PCOS) in the Han Chinese population. Four(More)
