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, or by damage ...

Nov 7, 2022 · Learn about the different patterns of inheritance for genetic disorders, such as autosomal dominant, recessive, X-linked, and mitochondrial. Find out how mutations, chromosomes, and environment affect the risk and expression of these diseases.
When the genetic disorder is inherited from one or both parents, it is also classified as a hereditary disease. Some disorders are caused by a mutation on the X chromosome and have X-linked inheritance. Very few disorders are inherited on the Y chromosome or mitochondrial DNA (due to their size). [3]
May 15, 2024 · There are several types of genetic disorders. Some disorders are caused by a genetic change (mutation) in a single gene; some are caused by an abnormality in one of the chromosomes; and some are complex, involving numerous genes and influences from environmental factors.
Learn about the causes, symptoms, and treatments of genetic diseases that affect humans. Explore the categories of chromosomal, single-gene, and multifactorial disorders, and how they are inherited and diagnosed.
