Medullary Sponge Kidney

Description

Medullary cystic kidney disease (MCKD) is an autosomal dominant form of tubulointerstitial nephropathy characterized by formation of renal cysts at the corticomedullary junction. It is characterized by adult onset of impaired renal function and salt wasting resulting in end-stage renal failure by the sixth decade (Wolf et al., 2004).Although early reports suggested that medullary cystic kidney disease and familial juvenile nephronophthisis (NPHP1 ) represented the same disease entity because of the overlapping phenotype (Chamberlin et al., 1977), they are now considered to be distinct disorders. MCKD has adult onset and shows autosomal dominant inheritance, whereas NPHP1 has juvenile onset and shows autosomal recessive inheritance (Christodoulou et al., 1998). NPHP1 is caused by mutation in the nephrocystin gene (NPHP1 ) on chromosome 2q13. Genetic Heterogeneity of Medullary Cystic Kidney DiseaseSee also MCKD2 (OMIM ), which is caused by mutation in the UMOD gene (OMIM ) on chromosome 16p.
