Please supply the correct answer.
The partnership between the Molecular Genetics Laboratory and the Ear and Hearing Center at Cincinnati Children's Hospital Medical Center allows for optimum care of your patients.
We are staffed by a team of experts who provide guidance in:
Clinical interpretations are written in conjunction with our nationally recognized pediatric otolaryngologist, board certified molecular and medical geneticists and genetic counselor. Each report is customized for your patient and includes a detailed interpretation of the genetic findings, the clinical significance of the results and specific recommendations for clinical management and additional testing, if warranted. These specialists are available to you for pre- or post-test consultation.

C. Alexander Valencia, PhD, is a biochemist and clinical molecular geneticist who has basic and translational research programs in genomics and proteomics. His laboratory studies the biochemical mechanisms of apoptosis through a novel proteomic method called mRNA-display. Moreover, his translational research program, in the area of clinical molecular genetics, addresses the implementation of new molecular diagnostic platforms, including next-generation sequencing, in clinical genetic testing.
