Congenital chloride diarrhoea (CCD) is a serious inherited defect of intestinal electrolyte absorption transmitted in an autosomal recessive way. The molecular pathology involves an epithelial Cl(-)/HCO(3)(-) exchanger protein, encoded by the solute carrier family 26 member 3 gene (SLC26A3) and known DRA (down regulated in adenomas) in the distal ileum and colon. Polyhydramnios, premature birth, ileus without meconium passage, hypochloremia, and hyponatremia are typical features of CCD in the neonate followed by chronic metabolic alkalosis, hypokalemia, hypochloremia, retarded growth and renal impairment in older children and adults if the disease is not adequately treated. Antenatal diagnosis if made on the basis of findings on ultrasonography-a non-invasive diagnostic test-can help in early management of the disorder immediately after birth and, thus, prevent the sequelae. We present an interesting case of CCD diagnosed antenatally and found to have congenital cataract, which is a unique occurrence not reported in literature so far.

Electrogenic Na(+)-HCO(3) (-) cotransporter NBCe1 is expressed in several tissues such as kidney, eye, and brain, where it may mediate distinct biological processes. In particular, NBCe1 in renal proximal tubules is essential for the regulation of systemic acid/base balance. On the other hand, NBCe1 in eye may be indispensable for the maintenance of tissue homeostasis. Consistent with this view, homozygous mutations in NBCe1 cause severe proximal renal tubular acidosis associated with ocular abnormalities such as band keratopathy, glaucoma, and cataract. The widespread expression of NBCe1 in eye suggests that the inactivation of NBCe1 per se may be responsible for the occurrence of these ocular abnormalities. In this review, we discuss about physiological and pathological roles of NBCe1 in eye.
