Impaired urinary acidification

MedGen UID:
1378965
Concept ID:
C4476921
Finding
Synonym: Renal acidification defect
 
HPO: HP:0031033

Definition

The kidney contributes towards acid-base homeostasis by excreting H+ ions and retaining bicarbonate. This process is known as acidification of the urine. The pH of urine ranges normally from 4.5 to 8. The inability to reduce the pH of the urine in a situation where it would be otherwise expected is known as an acidification defect. [from HPO]

Conditions with this feature

Autosomal dominant distal renal tubular acidosis
MedGen UID:
963849
Concept ID:
CN280572
Disease or Syndrome
Individuals with hereditary distal renal tubular acidosis (dRTA) typically present in infancy with failure to thrive, although later presentations can occur, especially in individuals with autosomal dominant SLC4A1-dRTA. Initial clinical manifestations can also include emesis, polyuria, polydipsia, constipation, diarrhea, decreased appetite, and episodes of dehydration. Electrolyte manifestations include hyperchloremic non-anion gap metabolic acidosis and hypokalemia. Renal complications of dRTA include nephrocalcinosis, nephrolithiasis, medullary cysts, and impaired renal function. Additional manifestations include bone demineralization (rickets, osteomalacia), growth deficiency, sensorineural hearing loss (in ATP6V0A4-, ATP6V1B1-, and FOXI1-dRTA), and hereditary hemolytic anemia (in some individuals with SLC4A1-dRTA).
