Autosomal recessive is one of several ways that a trait, disorder, or disease can be passed down through families. An autosomal whats the meaning of recessive trait disorder means two copies of an abnormal gene must be present in order for the disease or trait to develop.

One gene in each pair comes from the mother, and the other gene comes from the father. Recessive inheritance means both genes in a pair must be abnormal to cause disease. People with only one defective gene in the pair are called carriers.

These people are most often not affected with the condition. However, they can pass the abnormal gene to their children. If you are born to parents who both carry the same autosomal recessive gene, you have a 1 in 4 chance of inheriting the abnormal gene from both parents and developing the disease. This would make you a carrier. In other words, for a child born to a couple who both carry the gene but do not have signs of diseasethe expected outcome for each pregnancy is:.

Note: These outcomes do not mean that the children will definitely be carriers or be severely affected. Clinical genomics. Textbook of Family Medicine.
