Introduction
Autosomal Dominant Distal Renal Tubular Acidosis (AD-dRTA) is a rare disorder caused by a mutation in the AE1 gene. Learn more below.
Overview of Autosomal Dominant Distal Renal Tubular Acidosis
Autosomal Dominant Distal Renal Tubular Acidosis (AD-dRTA) is a rare genetic disorder primarily caused by mutations in the SLC4A1 gene on chromosome 7q21-22. This mutation affects the AE1 gene encoding the basolateral Cl- HCO3-exchanger, leading to impaired acid excretion. AD-dRTA can manifest with metabolic acidosis, defective urinary acidification, hypercalciuria, nephrolithiasis, hypokalemia, renal failure, and growth issues. AD-dRTA can present in infancy or adulthood with symptoms like failure to thrive, emesis, polyuria, and dehydration.
Clinical Features
Autosomal Dominant Distal Renal Tubular Acidosis (AD-dRTA) presents with metabolic acidosis, urinary acidification defects, hypercalciuria, nephrolithiasis, hypokalemia, renal failure, and growth issues. Explore the symptoms and manifestations below.
Presentation in Infancy and Adulthood
Autosomal Dominant Distal Renal Tubular Acidosis (AD-dRTA) may present differently based on the age of onset. In infants, symptoms like failure to thrive, emesis, polyuria, and dehydration can be observed. Adults may experience a milder form of the disease with metabolic acidosis and renal issues. Early detection and proper management are crucial for improving outcomes.
