What it is
Mucopolysaccharidosis type 2, attenuated form (MPS2att), the less severe form of MPS2, leads to a massive accumulation of glycosaminoglycans and a wide variety of symptoms including distinctive facies, short stature, cardiorespiratory and skeletal findings. It is differentiated from mucopolysaccharidosis type 2, severe form by the absence of cognitive decline.

ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
