Uromodulin

The protein product of the uromodulin gene is better known as Tamm-Horsfall protein, the most abundant protein excreted by normal urine. Although caused by mutations, the pathogenetic mechanism behind hyperuricemic nephropathy, medullary and glomerular cystic kidney diseases has yet to be elucidated.

Gene Structure

The gene consists of 12 exons, of which 11 are translated.
