Leukodystrophy, hypomyelinating, 2 - characteristic clinical symptoms of Pelizaeus-Merzbacher disease, onset infancy. Spastic paraplegia 44, autosomal recessive - mild symptoms were reported in the first or second decades, there was more severe progression with disability in the third decade - single family in OMIM. Milder subclinical leukodystrophy reported in a second family.AmberCreated: 2 Sep 2019, 4:06 p.m. | Last Modified: 2 Sep 2019, 4:06 p.m.
