The Center for Genetic Studies & Research (CGSR) is a newly established center running successfully for the past 8 years at The Madras Medical Mission, Chennai, providing genetic services with facilities for conducting diagnostics, counselling, academics and research housed with advanced equipment and technology. It is spread over 1200 sq. ft and includes state-of-the-art facilities from leading technology providers like Thermo Scientific, Olympus, Shimadzu, Abott Molecular, Eppendorf including a cytogenetic workstation coupled with Leica microscope and Cytovision software version 7.4 for carrying out clinical and molecular cytogenetic and DNA based molecular genetic tests. CGSR aims to provide strong commitment to research and the development of new services such as molecular genetics and cancer diagnosis and risk assessment by collaborating closely with clinical practice and healthcare providers in order to assist patients and their families in the understanding of the diagnosis, prevention and management of genetic disorders.

Highlights

  • The CGSR houses diagnostic services with an extensive range of cytogenetic testing such as prenatal and post–natal genetic screening, haemotological disorders, sperm aneuploidy tests (SAT), fluorescence in situ hybridisation (FISH), etc.
  • As per the PCPNDT Act of 1994, registration has been granted by the Government of Tamil Nadu to conduct prenatal genetic diagnosis. A dedicated Fetal Medicine Unit works hand-in-hand with CGSR to provide the prenatal testing services.
  • CGSR is involved in teaching genetics to various units of The Madras Medical Mission (MMM) such as B.Sc/M.Sc. Nursing, B.Sc/M.Sc. MLT, MBBS/MD students on a regular basis and conducting on–the–job training, observership, internship and projects on clinical genetics for students from life science, biotechnology, biomedical genetics and genetic engineering background.
  • Published 22 original research articles and reviews in peer-reviewed journals and presented 30 invited guest lectures/oral/poster presentations in national and international forums since the centre’s inception.
