Mucolipidosis is an autosomal recessive lysosomal storage disorder that demonstrates a clinical resemblance to mucopolysaccharidosis. Accumulation of glycoproteins throughout the body causes dysfunction of several organs, in particular, valvular heart diseases are an important cause of mortality, however, there is no consensus guideline regarding the indications and optimal timing of the surgical repair because of the unclear and short natural history. Here we present 12- and 15-year-old siblings diagnosed with mucolipidosis who underwent aortic valve replacement. The senior sibling received redo-aortic valve replacement for prosthetic valve dysfunction 11 years after the initial surgery. A few surgical valve replacements in patients with mucopolysaccharidosis have been reported, however, there is no published case of aortic valve replacements in two siblings with mucolipidosis.
