He is married to Amal Nassar and has three children.
He received his college and medical education at the American University of Beirut (AUB), Lebanon (1967), and his residency in pediatrics at AUB and Johns Hopkins University Hospital in Baltimore (1967-1970), as well as his fellowship training in pediatric nephrology at Georgetown University in Washington, D.C (1970-1972).
Dr Barakat is certified by the American Board of Pediatrics and the American Board of Hospital Physicians. Now he is Clinical Professor of Pediatrics and Pediatric Nephrology at Georgetown University, and also maintains a position of a Visiting Professor of Pediatrics at the University of Virginia.
- In 1974, Barakat et al suggested a unifying concept for "Drash syndrome" (nephropathy, Wilms' tumor, and genital anomalies). The syndrome is now called the "Denys-Drash syndrome," a name he suggested in 1988 (Barakat AY: Nomenclature of Drash Syndrome. Clinical Nephrology 29: 107, 1988, letter.).
- In 1977, Barakat et al described four siblings with familial nephrosis, nerve deafness, and hypoparathyroidism. This syndrome is now known as the "Barakat syndrome or "HDR syndrome" (Barakat AY, D'Albora JB, Martin MM, Jose PA: Familial nephrosis, nerve deafness, and hypoparathyroidism. Journal of Pediatrics 9l: 60, l977). The defect in the majority of cases of Barakat syndrome has mapped to chromosome 10p (Gene Map Locus: 10pter-p13 or 10p14-p15.1). Haploinsufficiency(deletions) or mutations of the GATA3 gene appear to be the underlying cause of this syndrome.
- In 1981, Barakat et al described a new syndrome of renal alkalosis, which is a variant of Bartter syndrome. (Barakat AY, Dabbagh S, de Chadarevian JP: Hypokalemic alkalosis, hyperreninemia, aldosteronism, normal blood pressure, and absence of juxtaglomerular apparatus hyperplasia: A variant of Bartter syndrome or a new syndrome of renal alkalosis. International Journal of Pediatric Nephrology 2: 259, l98l.
- In 1982, Barakat et al described for the first time the association of diffuse Mesangial cell sclerosis and ocular abnormalities.(Barakat AY, Khoury LA, Allam CK, Najjar SS: Diffuse Mesangial cell sclerosis and ocular abnormalties in two siblings. International Journal of Pediatric Nephrology 3: 33, 1982.).
- In 1985, Shehab and Barakat described, also for the first time, the association of Thalassemia B with distal renal tubular acidosis. (Shehab M, Barakat AY: Thalassemia B with distal Renal tubular acidosis: previously undescribed association. International Journal of Pediatric Nephrology 6: l43, 1985.).
- In 1988, Barakat et al reported previously un-described renal and cardiac anomalies associated with Townes-Brocks syndrome and consisting of truncus arteriosus, Ventricular septal defect, Renal agenesis, and renal Dysplasia. (Barakat AY, Butler MG, Salter JE, Fogo A: Townes Brocks syndrome: report of three additional patients with previously undescribed renal and cardiac abnormalities. Dysmorphology and Clinical Genetics 2: 104, 1988).
- In 1989-1991, Barakat et al reviewed 13,775 autopsies at Vanderbilt University and reported the association of congenital abnormalities of the kidney and urinary tract with those of other organs, and the occurrence of renal and urinary tract abnormalities.
- In 1996, Barakat et al reported for the first time the occurrence of hypoplastic kidneys in a patient with the Hajdu-Cheney syndrome, and suggested that renal anomalies ought to be an integral part of this syndrome.
- In 1999, Barakat and Castaldo reported for the first time the use of Oxandrolone in the prophylaxis of Hereditary Angioedema, a treatment which has helped many patients worldwide. (Barakat AJ, Castaldo, AJ: Successful use of oxandrolone in the prophylaxis of hereditary angioedema: A case report. Pediatric Asthma, Allergy and Immunology 13: 189, 1999).
- In 1989, Barakat reported the incidence of congenital abnormalities of the kidney and urogenital system in Lebanon (Barakat AY, Baasiri GM, Mounla NA: The incidence of congenital abnormalities of the kidney and urogenital system in Lebanon. Lebanese Medical Journal 24: 43, 1989). He also reported on the incidence of renal disease in Lebanon (Barakat AJ, Atiyeh BA: Renal disease in Lebanese children and adolescents: Findings in 118 consecutive percutaneous renal biopsies. Lebanese Medical Journal 46: 98, 1999).
- Between 1981 and 2008, Barakat contributed 23 chapters to major medical books. In 1986, he co-authored a book on "The Kidney in Genetic Disease, Barakat AY, Der Kaloustian VM, Mufarrij AA, Birbari AE. Edinburgh: Churchill Livingstone. In 1990, he edited a book entitled "Renal Disease in Children: Clinical Evaluation and Diagnosis, Barakat AY, Editor, New York: Springer-Verlag. In 2007, he edited the Arabic edition of the American Academy of Pediatrics "Caring for your Baby and Young Child: Birth to Age 5," and donated his effort to the Arab child. Dr. Barakat has just completed, along with Dr. Russell Chesney, editing a book entitled "Pediatric Nephrology for Primary Care to be published by the American Academy of Pediatrics in November, 2008.
