Study Details

Study Description

Brief Summary

This is a prospective observational study that aims to identify the underlying mechanisms of PolyCystic Ovarian Syndrome (PCOS) and associated comorbidities such as subfertility, miscarriage; and pregnancy complications such as gestational diabetes mellitus and Intrahepatic cholestasis of pregnancy (ICP). This will be achieved through cross-sectional observation and laboratory analyses.

Condition or Disease Intervention/Treatment Phase
  • Other: No intervention

Detailed Description

Here we propose a comprehensive program to dissect the underlying disease-causing mechanisms of PCOS and associated comorbidities. We will investigate how the different layers of biological information (ranging from DNA variant genotyping, to RNA sequencing and proteomics), and clinical characteristics are correlated with each other and how this affects PCOS in fat tissue derived cells, as well as ovarian tissue and tissue derived cells by using a combination of big data analysis, a range of "-omics" technologies, of both in-house generated and publicly available data, paired with state of the art statistical and bioinformatics analysis. Out of these mechanisms and pathways we will identify druggable targets for proposals for detailed functional follow up with an aim of development of novel therapeutic options for PCOS.

Outcome Measures

Primary Outcome Measures

  1. Identify the underlying genetic and pathophysiological mechanisms of PCOS and associated phenotypes [one visit]

    Questionnaire data, imaging analysis, medical records and sample analysis

Secondary Outcome Measures

  1. To identify novel biomarkers of PCOS and associated comorbidities. [one visit]

  2. To identify clinical subgroups of PCOS and associated comorbidities. [one visit]
