Casie Genetti, MS, CGC Research Coordinator/Genetic Counselor

Casie Genetti is a genetic counselor specializing in the genetics of congenital myopathies as well as rare and undiagnosed disorders. She received her Master’s degree in Genetic Counseling from Boston University in May 2015 and began working with the Beggs Congenital Myopathy Research Program at Boston Children’s Hospital in June 2015. She acts as a liaison between the laboratory and research participants/referring clinicians. She recruits study participants, designs recruitment materials, gathers and analyzes clinical data, as well as to responds to inquiries about inheritance patterns, research studies, and general information about the congenital myopathies. Casie also reports recent developments and coordinates follow up studies with referring physicians and CLIA-certified laboratories.

If you would like to contact Casie regarding her work in the Beggs lab or to ask general questions about our research, please write to:

Pankaj Agrawal, MD, Research Fellow

Assistant in Newborn Medicine, Boston Children's Hospital and Instructor in Pediatrics, Harvard Medical School

Dr. Agrawal's research consists of linkage analysis on a family with autosomal dominant multiminicore disease and non-specific myopathy. He is also working on the identification of candidate genes involved in multiminicore disease as well as screening the actin gene in patients with nemaline myopathy. 

Vandana Gupta, PhD, Research Fellow

Dr. Gupta's work is focused on understanding the genetic cause and developing therapies for congenital muscle diseases. She is using a combination of classical genetics and next generation technologies to identify genes causing congenital muscle diseases in human patients. She is using the zebrafish model to understand the function of new genes identified by genetic screens and next generation sequencing in skeletal muscle development. She has developed several zebrafish models in known as well as new gene candidates for muscle diseases (DAG1, LAMA2, MTMR12). The conserved genetics and skeletal muscle structure as well as ease of doing high throughput screens in these small animals make them a wonderful model to study neuromuscular diseases. She is currently developing therapies using zebrafish models by high throughput chemical screens to find cures for muscle diseases in the near future.


Behzad Moghadaszadeh, PhD, Research Fellow

Research Fellow in Genetics

Both alpha-actinin 2 and 3 are key components of the muscle sarcomere; they are located at the Z line and bind to actin filaments as well as many other sarcomeric proteins. Alpha-actinin 2 is expressed in slow and fast skeletal muscle, as well as cardiac muscle and brain. The expression of alpha-actinin 3 however, is limited to fast muscle fibers. Recent studies show that alpha-actinin 3 provides an advantage for power and sprint activities.
We hypothesize that despite their high homology, alpha-actinin 2 and 3 might have different functions. To address this question, Behzad is generating knock-in mice that do not express alpha-actinin 2 and express alpha-actinin 3 under the control of alpha-actinin 2 promoter.

Hanna Gazda's research focuses on identifying the genetic causes and molecular pathogenesis of Diamond-Blackfan Anemia (DBA), a bone marrow failure characterized by anemia, bone marrow erythroblastopenia and congenital abnormalities. The first DBA gene, ribosomal protein S19, was found to be mutated in ~25% of DBA patients. Gazda and colleagues recently identified four other genes, RPS24, RPL5, RPL11, and RPS7, mutated in ~15% of DBA patients, and confirmed that DBA is a first human disease caused by mutations in ribosomal proteins. They also discovered the first known correlation between mutations in certain genes and particular clinical findings. In particular, mutations in RPL5 are associated with multiple physical abnormalities including cleft lip/cleft palate, thumbs and heart anomalies, while isolated thumb malformations are predominantly present in patients carrying mutations in RPL11. The laboratory’s current goal is to identify other genes involved in DBA, to uncover the pathogenesis of the disease and to generate an animal model for DBA.
