NAGWA ABDEL MEGUID

Researcher, Egypt

Dr. Meguid is a professor of human genetics and head of the Department of Research on Children with Special Needs at the National Research Center (NRC) in Egypt. She holds a Ph.D. in Human Genetics, and she is a Senior Geneticist at the Genetics Institute, Pasadena, California; and a fellow of Uppsala University, Sweden. She was one of five selected scientists to win the outstanding L’Oreal UNESCO Award for women in Science for Africa and the Middle East (2002). She has used her expertise to identify and describe several novel genetic syndromes. She added new syndromes to the medical literature. She was given the Distinctive Arab Female Scientist Prize, Creative Women in Genetics, by the Arabian Gulf University, Bahrain, May, 2009. She was also given the National Award for Scientific Excellence in Advanced Technology in 2009. Furthermore, she was awarded the National Research Centre Appreciation Prize in Medical Sciences in 2011.

Dr. Meguid is the head and running a clinic for children with special needs in the NRC. She is one of the pioneers who accurately diagnosed, delineated and published autosomal recessive disorders in Egyptians as a consequence of the high prevalence of consanguinity. On the other hand she is the head of the laboratory of research in DNA and biochemical changes in genetic disorders. She participated in determining the spectrum of gene mutations causing common genetic disorders in Egypt (phenylketonuria, Duchenne muscular dystrophy, congenital sensorineural hearing loss and fragile-X syndrome) thus suggesting programs for their prevention by heterozygous detection and prenatal diagnosis. She is the first to delineate the prevalence of FX mutation among Egyptian males which was 0.9 per 1000. Moreover, it was 6.4% among mentally subnormal males.

In addition, Prof. Meguid initiated a special clinic for early intervention in the Medical Service Unit at the National Research Centre. She applied special evaluation programs to teach and assess the cognitive, language and motor skills.

Prof. Meguid is actively involved in training and teaching young physicians and scientists through a number of teaching and administrative posts. She also reaches out to her community by offering lectures to parents, schools and health care workers in Cairo and distant governorates and writing newspaper articles and on-line especially for women to increase awareness of genetic disorders and the value of genetic counseling. "As the mysteries of the human genetic code are unraveled, women need protection so that breakthroughs are used to treat and heal, not to isolate and discriminate." Dr. Nagwa Abdel Meguid writes of the potential for unethical use of genetic information and calls for strict guidelines to ensure privacy for individuals and knowledge-sharing for scientists.

Dr. Nagwa Meguid, a professor of human genetics, uses her field as an example of what women can accomplish for science, for society and themselves. Genetics also happens to be the science that proved women are just as capable as men. She is a member in the National Committee for Women in Science and Technology, member of the International Jury L’OREAL-UNESCO Awards "For Women in Science" 2008 - 2011. She has extensive experience in training postgraduate students. She supervised around 25 PhD students and 27 master theses in medicine and neuroscience, human genetics and psychiatry. She has more than 130 national and international publications in the field of neuroscience and human genetics. She is a peer reviewer for scientific journals such as; Disease Marker Journal and Neuroscience Letters as well as being a member of TOWAS, and of the Neuroinsight Foundation for Brain Research Initiatives, Canada. She is the principal Investigator of the Canadian- Egyptian Neurodevelopmental Study, and a member of Gender Research in Africa into Information Communication Technologies for Empowerment (GRACE), International Development Research Centre in Canada (IDRC). She is a member of the Bioethics Network on Women's Issues in the Arab Region, 2011, and editorial board member of Autism-Open Access, OMICS Publishing group; An Open Access Publisher for Advancement of Science and Technology.

Recently, Dr Meguid shared in the discovery of inactivating mutations in the gene BCKDK (Branched Chain Ketoacid Dehydrogenase Kinase) in consanguineous families with autism, epilepsy and intellectual disability. BCKDK knockout mice showing abnormal brain amino acid profiles and autistic neurobehavioral deficits that respond to dietary supplementation. Thus, autism presenting with intellectual disability and epilepsy caused by BCKDK mutations represents a potentially treatable syndrome (September 7, 2012 http://www.sciencemag.org/content/current).
