Medical genetics is concerned with how diseases, birth defects, or other health problems are inherited or passed down from one generation to the next through the genes. Genes are the building blocks of heredity that hold DNA, the instructions for making proteins. Proteins do most of the work in cells by moving molecules to where they are needed, building structures, breaking down toxins and doing general clean up and maintenance work around the body.
Sometimes there is a mutation or a change in a gene or genes. This effects the gene's instructions for making a protein. If the protein is missing or not working properly, this causes a medical condition known as a genetic disorder.
- Single-gene disorders, where a mutation affects one gene. Sickle cell anemia is an example.
- Chromosomal disorders, where chromosomes (or parts of chromosomes) are missing or changed.
- Complex disorders, with mutations in two or more genes. Often lifestyle and environment also play a role.
The physicians who practice at Children’s Health are all certified by the American Board of Medical Genetics and have extensive clinical experience. Every person in the entire genetic counseling group has at least a master’s degree in the field.
Medical Genetics offers evaluation and testing, information about specific genetic diseases, family history analysis, and chromosomal, metabolic and DNA analysis for the diagnosis of diseases. Counselors can assist with genetic counseling and discussions of options for having children. Social workers can link the family to other medical specialists as needed, as well as community resources and support groups.
