Genetic Diseases

A genetic disorder is a genetic problem caused by one or more abnormalities in the genome, especially a condition that is present from birth (congenital). Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or structure of entire chromosomes, the structures that carry genes).
