Shown are pertinent molecular and clinical details. Mutations in AQP2 are all homozygous, except for Patient 25, who is compound heterozygous.

‘?’ is standard genetic annotation for Unknown.

Uosm, urine osmolality; PUV, posterior urethral valves; VUR, vesico-ureteric reflux; IUGR, intra-uterine growth retardation.
