A description of the three genetic disorders

Most genetic disorders are caused by defective genes on the autosomes if an autosomal genetic disorder is caused by a problem with a single gene, then the following rules of inheritance usually apply there are exceptions to these rules, but they are useful guidelines for understanding inheritance. Human genetic disease: human genetic disease, any of the diseases and disorders that are caused by mutations in one or more genes with the increasing ability to control infectious and nutritional diseases in developed countries, there has come the realization that genetic diseases are a major cause of disability, death. 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 to chromosomes (changes in the number or structure of entire chromosomes, the structures that carry genes. Genetic disorders are caused by changes in the structure or number of the a down syndrome individual has three copies of chromosome 21 when there should. A gene codes for a protein, which does a job in the body the effects of a genetic disorder depend on the protein’s job a single gene disorder is caused by variations (or mutations) in the dna sequence of a specific gene the dna changes affect the product that the gene codes for—usually a. Autosomal dominant means that a person only needs one copy of the changed gene (genetic difference) in order to have the disorder usually, the changed gene is inherited from a parent who also has the disorder and every generation in the family may have members with the disorder.
