Genetic Medicine and Metabolism
The Medical Genetics and Metabolism department offers comprehensive services to children with suspected genetic conditions. We are often asked what a genetic condition is – to put it simply, a genetic condition is any type of medical condition caused by changes in the DNA. Sometimes these conditions are hereditary, and sometimes they are not. We are one of the largest medical genetics providers in the Central Valley, providing services to families across the state.
Our services include comprehensive physical exams, analysis of family history, genetic testing and genetic counseling. We provide both in-person and telemedicine consultations and review inheritance, prognosis and treatment, when available, for people diagnosed with genetic conditions. Our team includes board-certified and board-eligible physician geneticists, licensed and certified genetic counselors, nurse coordinators, as well as a metabolic dietitian and social worker.
We are certified as a California Children’s Services (CCS) Metabolic Treatment Center for the CA Newborn Screening Program. Our team works with reproductive medicine as part of the prenatal diagnostic center care team at Valley Children’s Maternal Fetal Center. Our physician services are available 24 hours a day, 7 days a week.
