A 35-year-old woman presents with dull, persistent flank and abdominal pain, polyuria, nocturia, and frequent urinary tract infections. Physical examination is notable for blood pressure of 150/90 mm Hg and multiple bilateral abdominal masses. Urinalysis is notable for microscopic hematuria and 1+ protein. CT of the abdomen reveals multiple cysts in the kidneys. The patient notes that she was adopted and knows nothing about her family medical history. What is the most likely etiology of this patient’s illness?
(A) A mutation on chromosome 3
(B) A mutation on chromosome 6
(C) A mutation on chromosome 9
(D) A mutation on chromosome 16
