What it is
A rare disorder of plasmalogen biosynthesis characterized by syndromic severe intellectual disability with congenital cataracts, early-onset epilepsy, microcephaly, global developmental delay, growth retardation and short stature, and spastic quadriparesis. Dysmorphic facial features may be present, including high-arched eyebrows, flattened nasal root, hypertelorism, and long and smooth philtrum. Rhizomelia is not part of the syndrome. Cerebellar atrophy, white matter abnormalities, and Dandy-Walker malformation have been described on brain imaging.

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.
