hereditary syndrome

(heh-REH-dih-tayr-ee SIN-drome)
A disorder caused by mutations (changes) in certain genes or chromosomes that are passed down from parent to child. Hereditary syndromes may be inherited from one or both parents, and several close family members (such as a mother, daughter, and sister) may have the same disorder.
