Dr. Ramakrishnan V serves as an Associate Professor of Genetics at the Faculty of Allied Health Sciences, Chettinad Hospital and Research Institute, part of the Chettinad Academy of Research and Education in Kelambakkam. His expertise provides vital insights into genetic polymorphisms linked to various metabolic disorders, which are important for both clinical practice and public health. He is also actively involved in chromosomal analysis for numerous genetic disorders identified in the pediatric cases. His research focuses on finding chromosomal abnormalities and structural changes that cause developmental issues and congenital diseases in children. This research is crucial for early identification, clinical care, and genetic counselling for afflicted families. When conducting a genetic evaluation of an individual, it is essential to consider the family medical history. A thorough pathological background of the family aids in identifying or predicting inherited genetic disease patterns within or across families. In recent years, genetic testing has become increasingly important for the evaluation of cardiac, metabolic, reproductive, and neurological conditions. Advances in technology, including polymerase chain reaction, DNA sequencing, multi-omics, and systems biology techniques, have facilitated the shift toward multigene testing using microarray panels. These panels, which include hundreds of biomarker genes, enable early detection of complex diseases.Sheena Mariam Thomas is working in a research associate position under Dr. Ramakrishnan's supervision at the Faculty of Allied Health Sciences, Chettinad Hospital and Research Institute, part of the Chettinad Academy of Research and Education.
