In addition, patients with HNF1β nephropathy often present with symptoms beyond a Gitelman-like phenotype including, but not limited to, tubule interstitial kidney disease (ADTKD), renal cysts, renal hypoplasia, hyperuricemia, hyperparathyroidism, maturity-onset diabetes of the young (MODY5), neurodevelopmental disorders, or genital and urinary tract malformations [64,69–72]. The gene discussed is HNF1B; the disease is autosomal dominant medullary cystic kidney disease with or without hyperuricemia.
