Building on a Strong Foundation: TCGS leverages data from the Tehran Lipid and Glucose Study (TLGS), a long-running cohort study that has followed over 15,000 participants for over 20 years.
Family-Based Approach: TCGS expands on TLGS by including over 20,000 participants from four ongoing family-based studies. This allows researchers to explore the role of genetics in health and disease.
Diversity and Data Collection: The study incorporates a diverse range of ethnicities within the Iranian population. Extensive data is collected on demographics, health history, lifestyle factors, and genetic information.
Advanced Genotyping: Over 16,000 participants have been genotyped using advanced technology, providing valuable insights into the genetic makeup of the Iranian population.
Consanguinity Analysis: The study investigates the prevalence of consanguineous marriages within the population using genetic data.
Comprehensive Health Information: TCGS utilizes the ICD-11 classification system to categorize participants' health conditions, allowing for detailed analysis of prevalent diseases.
