Clinical Genetics Service
The goal for a trainee during the Clinical Genetics service is to become a medical geneticist. This will involve seeing at least 150 patients within an inpatient and outpatient tertiary care setting. These patients will include those with disorders of mendelian genetics, cytogenetics, contiguous gene deletions, dysmorphology, congenital malformations, multifactorial disorders, mental retardation and developmental disabilities.
In addition, the trainee will see patients who have questions regarding prenatal diagnosis and teratology. Clinical medical geneticists should be able to:
- Diagnose and manage genetic disorders
- Provide patient and family counseling
- Use knowledge of heterogeneity, variability, and natural history of genetic disorders in patient-care decision making
- Elicit and interpret individual and family medical histories
- Interpret clinical genetics and specialized laboratory testing information
- Explain the causes and natural history of genetic disorders and genetic risk assessment
- Interact with other health-care professionals in the provision of services for patients with genetically influenced disorders
Objectives

- Present the case to the attending physician and to other clinic attendings and genetic counselors
- Reassess the differential diagnosis
- Plan tests necessary to arrive at a definitive diagnosis
- Under guidance of attending physician, explain plan to patient and/or patient’s parents
