An autosomal recessive disorder means two copies of an abnormal gene must be present in order for the disease or trait to develop. An autosomal recessive disorder means two copies of an abnormal gene must be present in order for the disease or trait to develop.
Print. To have an autosomal recessive disorder, you inherit two mutated genes, one from each parent. These disorders are usually passed on by two carriers. Their health is rarely affected, but they have one mutated gene (recessive gene) and one normal gene (dominant gene) for the condition.  Only one mutated copy of the gene will be necessary for a person to be affected by an autosomal dominant disorder. Each affected person usually has one affected parent. The chance a child will inherit the mutated gene is 50%. 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). Most genetic disorders are quite rare and affect one person in every several thousands or millions. The parents are carriers who have only one copy of the gene and do not exhibit the trait because the gene is recessive to its normal counterpart gene. If both parents are carriers, there is a 25% chance of a child inheriting both abnormal genes and, consequently, developing the disease. Other examples of autosomal recessive disorders include: 1  Canavan disease of the brain. 2  Congenital neutropenia, a blood condition. 3  Ellis-van Creveld syndrome, a birth defect. Definition. Autosomal recessive is one of several ways that a trait, disorder, or disease can be passed down through families. An autosomal recessive disorder means two copies of an abnormal gene must be present in order for the disease or trait to develop. It also depends on whether the trait is dominant or recessive. A mutation in a gene on one of the first 22 nonsex chromosomes can lead to an autosomal disorder. Genes come in pairs. One gene in each pair comes from the mother, and the other gene comes from the father. Print. In an autosomal dominant disorder, the mutated gene is a dominant gene located on one of the nonsex chromosomes (autosomes). You need only one mutated gene to be affected by this type of disorder.  Definition of Recessive, autosomal. Recessive, autosomal: A genetic condition that appears only in individuals who have received two copies of an autosomal gene, one copy from each parent. The gene is on an autosome, a nonsex chromosome.  Information. Inheriting a specific disease, condition, or trait depends on the type of chromosome that is affected (autosomal or sex chromosome). It also depends on whether the trait is dominant or recessive. A mutation in a gene on one of the first 22 nonsex chromosomes can lead to an autosomal disorder. Genes come in pairs. One gene in each pair comes from the mother, and the other gene comes from the father. Autosomal recessive inheritance means that the gene in question is located on one of the autosomes. These are numbered pairs of chromosomes, 1 through 22. Autosomes do not affect an offspring's gender. Recessive means that two copies of the gene are necessary to have the trait or disorder.  Autosomal recessive. A pattern of inheritance in which both copies of an autosomal gene must be abnormal for a genetic condition or disease to occur. An autosomal gene is a gene that is located on one of the autosomes or non-sex chromosomes. In autosomal recessive inheritance, both genes of interest (i.e., one from each parent) on a paired chromosome have the same defect; if both parents have the recessive gene of interest, the likelihood of expression in progeny is 1:4. Men and women are affected equally. Examples.
