Medical Genetics focuses on how changes in genes and chromosomes affect health. This page explains when a genetic evaluation may be useful, common types of genetic tests, and what genetic counseling typically covers. This information is educational only — consult a specialist for personalized recommendations.
Medical Genetics assesses inherited conditions, congenital anomalies, and genetic factors that influence disease risk. Care can include evaluating family histories, testing for single-gene disorders, chromosomal analyses, and assessing cancer predisposition syndromes. Genetic counselors and clinical geneticists help interpret results and explain implications for family members.
Seek genetic assessment if there is a family history of a known genetic disorder, repeated pregnancy loss, a child with developmental delay or congenital malformations, or clustering of certain cancers in relatives. Couples considering parenthood who want information about carrier status may also benefit. For urgent, life‑threatening symptoms, contact emergency services.
Tests range from chromosome-level studies (karyotype), microarray analysis, targeted single‑gene tests and multigene panels, to carrier screening and prenatal options such as noninvasive prenatal testing (NIPT) or diagnostic procedures. The choice of test depends on clinical findings, family history, and pregnancy status; a specialist recommends the most appropriate approach.
Genetic counseling provides pre‑ and post‑test information about test limits, possible results, and the implications for affected individuals and relatives. Management often involves coordination between Medical Genetics and specialties like Pediatrics, Obstetrics, or Oncology to plan follow‑up, surveillance, or supportive care as needed.
