Medullary cystic kidney disease (MCKD) is a chronic, progressive kidney disease characterized by the presence of small renal cysts that eventually lead to end stage renal failure. Symptoms typically appear at an average age of 28 years and may include polyuria (excessive production or passage of urine) and low urinary osmolality (decreased concentration) in the first morning urine. Later, symptoms of renal insufficiency typically progress to include anemia, metabolic acidosis and uremia. End stage renal disease (ESRD) eventually follows. There are 2 types of MCKD, which are both inherited in an autosomal dominant manner but are caused by mutations in different genes. MCKD 1 is caused by mutations in the MCKD1 gene (which has not yet been identified) and MCKD 2 is caused by mutations in the UMOD gene. The 2 types also differ by MCKD 1 being associated with ESRD at an average age of 62 years, while MCKD 2 is associated with ESRD around 32 years and is more likely to be associated with hyperuricemia and gout. Treatment for MCKD may include correction of water and electrolyte imbalances, and dialysis followed by renal transplantation for end-stage renal failure.[1]
