....especially muscles. The defect is due to a mutation in the gene that codes for an enzyme, acid alpha-glucosidase that is normally found in lysosomes. The enzyme normally breaks down glycogen into glucose, but mutations in the gene prevent the enzyme from breaking down the glycogen so that it bulds up in muscle cells, eventually damaging cells throughout the body. Infants with the disorder typically exhibit symptoms such as muscle weakness, and enlarged liver and heart, and heart failure. Most infants with Pompe disease cannot hold up their heads or move normally. As the disease progresses swallowing may become difficult and the tongue may become abnormally enlarged. Most children do not survive beyond the age of 1. The disease affects about 1 in 40,000 people. A man who had a brother that died of Pompe disease marries a woman who is heterozygous for the disease. What is the probability that their children will have the disease??

Boys with Lowe syndrome are born with cataracts in both eyes which are usually removed at a few months of age. Glaucoma is present in about 50% of the boys with Lowe syndrome. though usually not at birth. Slowly progressive renal failure if the major cause of mortality, with death usually occurring in the second or third decade of life. About 1/3 of patients have profound mental retardation, but most have IQ's in the moderate range of 40-54. It is a hereditary condition that affects only males, caused by a single defective gene in a gene called OCRL1. Because of this defective gene an essential enzyme called PIP2-5-phosphhatase is not produced. This enzyme is localized in the Golgi apparatus and appears to play a role in cellular trafficking. Deficiency of this enzyme may impair proper cellular protein sorting. A normal man and normal woman have had one male child who dies of Lowe syndrome. What is the probability that their next child will be affected with the syndrome?

It is an autosomal recessive disorder. It occurs equally in males and females, and found in all ethnic groups; it can affect all systems of the body, and many patients eventually develop acute myelogenous leukemia at an early age; they also develop a variety of other head, neck, gynecological and or gastrointestinal cancers; the patient can be cured of the FA blood problem by having a successful bone marrow transplant, but must still have regular examinations to watch for signs of cancer. A couple (both with FA) who have already had one child with FA decide that they would like to have another child.

a.) What was the genotype of the child with FA?

b.) What is the probability that their next child will have FA?
