This discovery is not only a breakthrough in understanding brain disorders, but also highlights the rising influence of Indian researchers in the global genomics field. The identification of EPB41L3 as a causative gene for developmental disorders demonstrates how international collaboration is vital to unlocking the mysteries of rare genetic diseases and improving patient outcomes worldwide.
In a scientific breakthrough, a collaborative research team led by Dr. Anju Shukla, from Kasturba Medical College, Manipal Academy of Higher Education (MAHE), Dr. Stephanie Bielas from the University of Michigan in the US, and Dr. Quasar Padiath from the University of Pittsburgh in the US, has identified a new genetic disorder linked to a defect in the EPB41L3 gene.
This discovery, published in the scientific journal Brain, sheds light on a disorder that causes seizures, developmental delay, decreased muscle tone, and defects in myelination — a process vital for the protection and insulation of nerves in the brain.
The study was co-authored by Dr. Purvi Majethia, Dr. Elizabeth Werren, and Dr. Guillermo Rodriguez Bey, alongside several other distinguished contributors from around the globe. According to MAHE, the research emphasises the critical role that global collaboration plays in advancing genetic science, particularly in rare disorders.
“This is the first time that alterations in the EPB41L3 gene have been linked to a brain disorder. Discovering a new gene associated with a condition is an exhilarating achievement for any research team. It’s a major milestone for myelin disorder research and will provide much-needed answers to families who have long sought diagnoses,” according to Dr. Anju Shukla, Principal Investigator of the research from MAHE.
The journey of discovery began when Dr. Shukla and her team clinically evaluated the genomic data of a four-year-old boy who exhibited seizures, developmental delay, and hypotonia at the Department of Medical Genetics, Kasturba Medical College. The team’s thorough genetic analysis revealed the EPB41L3 defect as a likely cause.
By collaborating with international researchers, four additional families from France, Egypt, and Pakistan with similar symptoms were identified, further solidifying the gene’s link to this disorder.
Dr. Padmaraj Hegde, Dean of Kasturba Medical College, praised the team’s achievements. “This discovery is yet another testimony to MAHE’s dedication to cutting-edge genetic research and reflects our longstanding commitment to improving pediatric care. The ability to connect genetic findings across international borders showcases the importance of scientific collaboration.”
