In a collaborative effort with researchers from our lab at inStem and NCBS, a study published in PNAS showed that air pollutants cause irregular heartbeats in bees and mis-expression of cardiac ion channel genes. This is alarming as such an effect might have huge implications on human heart health also.

Our work on the molecular genetics of cardiomyopathies led to a major discovery as we unraveled an ancient Myosin Binding Protein c3 (MYBPC3) gene deletion as a major risk factor for South Asians. To date, approximately 60 million people carry the heterozygous deletion. This variant, in its homozygous nature, causes severe childhood cardiomyopathies. Of note, this discovery was the subject of a documentary by Dr. Sanjay Gupta of CNN.

Please click the youtube video shown below for more details.

We discovered the variants in RAF1 (a RAS-MAPK member) as a primary cause of childhood-onset DCM (~10%). This is the first gene causing isolated DCM to be strongly associated with pediatric-onset disease and the first report of DCM principally attributable to altered RAS-MAPK signaling. Implications of these study on public health include various companies across the world use these variants as diagnostic
markers to identify the risk associated with cardiomyopathies.

In the current issue of the Journal of Molecular and Cellular Cardiology (July 2011), Dhandapany et al. further explore the ability of Raf1 to regulate hypertrophy of cardiomyocytes. The authors employ three common Raf1 mutations observed in Noonan/LEOPARD syndromes to dissect downstream signaling pathways ultimately impacting myocyte growth control.

Cardiovascular diseases (CVDs) are the leading cause of mortality globally. They are caused by various disorders of the heart and blood vessels. We are interested in understanding three major forms of CVDs including, cardiomyopathies, congenital heart disease and coronary heart disease (heart attacks).

We are a multi-disciplinary team including Geneticists, Clinicians, Bioinformaticians, Engineers, Biochemists, Biophysicists, and Molecular Biologists addressing CVDs through a multi-level approach.

The long-term goals of my group are to explore new genes, mechanisms and relevant drugs that have significant clinical and curative impact on CVDs.
