How is argininemia inherited?
Argininemia is inherited in an autosomal recessive manner. This is one way a disorder or trait can be passed down through a family. Everyone has two copies of the ARG1 gene; one received from their father and one from their mother. Autosomal recessive inheritance means that a person receives a nonworking copy of the ARG1 gene from both parents. The parents have one working copy of the gene and one nonworking copy; they are carriers for argininemia. Carriers do not develop symptoms of the disorder. If two people are carriers, there is a 25% chance with each pregnancy that the child will have the disorder and a 50% chance the child will also be a carrier for the disorder. If you have a family member with argininemia and you would like to know if you are a carrier, talk to your doctor or meet with a genetic counselor to discuss testing options.
