Patients who manifest the disease have 2 mutant alleles, while carriers of the mutation have only 1 mutant allele. The offspring of an individual with the disease and an individual who carries the allele has a 50% chance of developing the disease. 75% Cystinuria is inherited in an autosomal recessive pattern. The couple's child has a 0% chance of developing cystinuria. 100% An example of a 100% chance of a child developing cystinuria is when both parents have fully manifest disease (both carry 2 mutant alleles). In that case all offspring would have the disease too. Biochemistry Genetics A 27-year-old man presents to the emergency department with severe left flank pain for the past 3 hours. He states the pain is a sharp, stabbing sensation that radiates to his left groin. Upon further questioning, the patient recalls that he has had similar episodes in the past. Physical examination is remarkable for left costovertebral angle tenderness. Urinalysis demonstrates hematuria and hexagonal-shaped crystals. Following further investigation, the physician explains to the patient that his condition is caused by a genetic disorder characterized by a mutation in an amino acid transporters in the kidneys. If genetic testing reveals the patient's wife does not carry a similar mutation, what is the percentage that this couple's child will have the disease?
