Alpоrt syndrоme (AS) is а genetic diseаse in which а mutatiоn affects the kidneys, the ears, and the eyes. The syndrome was named for Dr. Alport who in 1927 described a British family in which many members developed kidney disease as well as deafness. He noted that affected men in the family died early as a result of their kidney problems, whereas females lived until old age and showed mild symptoms. The gene responsible for Alport syndrome is located on the X chromosome. Susan and Philip have 2 children. Their 12-year old son, Joe already has kidney problems while their 15-year old daughter Marianne is healthy. Susan had a brother who died of Alport syndrome but her parents are both over 60 years old. A. What are the genotypes for Susan and Philip? B. If Susan and Philip are expecting another child.
