The nurse is assessing the knowledge of new parents with a child born with maple syrup urine disease (MSUD). This is an autosomal recessive inherited disorder, which means that:
The disorder occurs in males and heterozygous females.
The disorder is carried on the X chromosome.
Both genes of a pair must be abnormal for the disorder to be expressed.
Only one copy of the abnormal gene is required for the disorder to be expressed.
The Correct Answer is C
Both genes of a pair must be abnormal for the disorder to be expressed. In autosomal recessive inheritance, the gene for the disorder is located on an autosome (any chromosome other than a sex chromosome) and a person must inherit two copies of the abnormal gene (one from each parent) in order for the disorder to be expressed. If a person inherits only one copy of the abnormal gene, they are a carrier of the disorder but do not typically show symptoms.
