Fried Inheritance

Fried syndrome is an autosomal recessive disorder.

To have an autosomal recessive disorder, you must inherit two mutated genes, one from each parent. Recessive disorders are usually passed on by two carrier parents. A carrier’s health is rarely affected, but they have one mutated gene and one normal gene for the condition. Two carriers have a 25 percent chance of having an unaffected child with two normal genes, a 50 percent chance of having an unaffected child, who also is a carrier, and a 25 percent chance of having an affected child with two copies of the abnormal genes.
