Abstract
Congenital chloride-losing diarrhea(CCD) is a rare autosomal recessive disease,characterized by disturbance of intestinal Cl-/HCO3-exchange caused by mutations in the SLC26A3(the solute-linked carrier family 26 member A3) gene.The main clinical feature of CCD is persistent,life-long watery diarrhea started from newborn,which leads to severe electrolyte disturbances with metabolic alkalosis,hypochloremia,hyponatremia,and hypokalemia.Diagnosis can be confirmed on the basis of high fecal chloride concentration( 90 mmol/L).The prognosis is good with an early diagnosis and replacement therapy.
