Autosomal Recessive ConditionsTopic OverviewAutosomal recessive conditions are genetic diseases that are passed to a child through both parents' chromosomes . Each person inherits 23 chromosomes from each parent and so has 23 pairs of chromosomes. Each chromosome contains genes . One or both of the chromosomes in a pair may contain a changed (mutated) gene that could cause a genetic disease. In an autosomal recessive condition, both chromosomes in a pair must have a changed gene for the person to have the condition. If only one chromosome has a changed gene, the person is a carrier and does not have symptoms. If both parents carry the gene change, there is a:
If only one parent carries the gene change, there is a 50% chance in each pregnancy that the child will:
If neither parent carries the gene change, the child will not have this type of condition. See a diagram of the chances of passing on an autosomal recessive condition . Autosomal recessive conditions include Tay-Sachs disease , cystic fibrosis , sickle cell disease , autosomal recessive polycystic kidney disease (ARPKD), and phenylketonuria (PKU).
