Coarse facial features are commonly seen in children with lysosomal storage diseases (eg. mucopolysaccharidoses, mucolipidoses, certain sphingolipidoses, and disorders of glycoprotein degradation). While the facial dysmorphisms can be subtle in early infancy, with age they become increasingly prominent due to build up of incompletely degraded substrates. Examples of "coarse" facial features include thickened eyebrows and frontal bossing. Subtler signs that can be seen even in infancy include "filling in" around the bridge of the nose and the nasolabial folds.
