CCBE1 mutation causing sclerosing cholangitis: Expanding the spectrum of lymphedema-cholestasis syndrome.

A 52-year old patient presented with lymphedema, protein loosing enteropathy, and sclerosing cholangitis and was diagnosed with lymphedema cholestasis syndrome (LCS). Cholangioscopy revealed dilated lymphatic vessels obstructing the bile duct and compound heterozygosity for collagen and calcium-binding epidermal growth factor domain-containing protein 1 (CCBE1) mutations was identified defining a novel type of LCS.
