Details
Human/Medical Genetics Genetic and Molecular analysis of inherited disorders, mapping genes, screening mutations, DNA based diagnostics and its application in biomedical problems Research in our laboratory focuses on the identification, localization (genetic loci) and characterization of genes responsible for the inherited genetic disorders and complex traits in human populations. Our approach for studying these events follows population genetics, linkage-based mapping, molecular genetics and statistical genetics. We utilize different forms of linkage analysis, mutation analysis, genome wide association studies and gene expression studies. The main aim of these studies is to identify the genes that are influenced by variants to predispose to these diseases, and to understand the etiopathogenesis from genetic variation to clinical disease. The long term aim is to transfer this knowledge to applications, such as development of genetic diagnostics and treatments, in humans.
