Human/Medical Genetics & Molecular Diagnostics

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.

Current projects aimed in our lab

• Investigation of the gene expression and characterization of selected genes associated with otosclerosis
• Identification of Genetic Susceptibility to Chronic or Recurrent Otitis Media with Effusion
• Molecular Genetic studies of congenital hearing impairment
• Genetic Analysis of Otosclerosis: Mapping Gene(s) and Screening of Candidate Genes for Mutations
• Understanding the genetic basis and molecular mechanisms of paediatric rare genetic disorders
