May 18, 2018 · A genetic disorder is a disease caused in whole or in part by a change in the DNA sequence away from the normal sequence. Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors ...
Nov 7, 2022 · Genetic disorders are diseases caused by an abnormal gene, often described as a mutation. When such diseases are inherited (rather than the result of a random mutation), it means they are passed along to a child from one or both parents, often according to certain patterns of inheritance.
