Biographical Sketch 
Daniel Sharer received his PhD in Biochemistry and Molecular Biology from Rutgers University in 1994. Dr. Sharer performed postdoctoral research at the National Cancer Institute and Emory University from 1996 - 2001. He then completed American Board of Medical Genetics (ABMG) training in Clinical Biochemical Genetics from 2002 - 2004, becoming board-certified in this specialty in 2005. Dr. Sharer is currently a Professor of Genetics and has been Director of the UAB Biochemical Genetics and Metabolic Disease Laboratory since 2005. Dr. Sharer is also the Director of the UAB Laboratory Genetics Fellowship Training Program, a member of the ACGME Residency Review Committee, the ABMG Board of Directors, and President of the Southeast Regional Genetics Group (SERGG).

Research/Clinical Interest
Clinical Biochemical Genetics
The primary goal of the Biochemical Genetics Laboratory (BGL) is to provide diagnostic services focusing on inborn errors of metabolism (IEM). These genetic disorders commonly present in neonates or young children and may rapidly cause irreversible brain damage or death if not identified and treated in a timely fashion. The advantage of biochemical analysis in these cases is the ability to quickly measure levels of genetically determined metabolites, such as amino acids, which may lead to rapid identification and treatment of an otherwise catastrophic condition. It is estimated that at least 1% of all cases of sudden infant death syndrome (SIDS) are caused by undiagnosed IEMs, several of which can be treated by nothing more than a specialized diet. Biochemical methods are now being widely employed for expanded newborn screening, which can identify affected infants before symptoms appear. The BGL is equipped with three core technologies: gas chromatography/mass spectrometry (GC/MS), automated amino acid ion exchange liquid chromatography, and liquid chromatography/tandem mass spectrometry (LC/MS/MS). Utilizing these instruments it is possible to identify a significant number of IEMs, including defects in amino and organic acid metabolism (including urea cycle disorders) and fatty acid oxidation disorders. The lab is also one of the few in the country that offers testing for creatine deficiency syndromes, a significant metabolic cause of MR and autism, as well as polyol analysis for disorders of the pentose phosphate pathway. Future diagnostic capabilities will include lysosomal storage disorders and galactosemia.
