A kidney disorder of impaired net acid secretion by the distal tubule characterized by hyperchloremic metabolic acidosis. Primary distal renal tubular acidosis is often associated with hypokalemia whereas acquired form may be associated with hypokalemia, hyperkalemia or normokalemia.
Features include very common findings: Nephrocalcinosis, Chronic metabolic acidosis, Hypokalemia, and Low bone density (reduced bone mineral density) and others; and common findings: Renal potassium wasting, Nephrolithiasis, Muscle weakness, and Failure to thrive and others. 38 total HPO annotations.

Recent research expands the phenotypic spectrum of WDR72-associated distal renal tubular acidosis by identifying renal cysts as a notable feature. This discovery may enhance understanding and diagnosis of the condition.
A case report highlights distal renal tubular acidosis as a renal manifestation of Sjögren's syndrome, contributing to the understanding of this rare disease's complications. This finding may inform future research and clinical approaches to managing patients with Sjögren's syndrome.
