Abstract

A 3-year-old girl with rhizomelic chondrodysplasia punctata (RCDP) had severe microcephaly but a normal gyral pattern, neuronal density, and cortical cytoarchitecture. The white matter was diffusely decreased in mass but normally myelinated. There was optic atrophy and cerebellar degeneration. Leukodystrophy in peroxisomal disorders is caused by elevated very long chain fatty acids. The absence of a fatty acid abnormality in RCDP explains the normal myelination. Cerebellar and retinal degeneration and possible stunted dendritogenesis may be due to plasmalogen deficiency, which is the most severe biochemical abnormality in RCDP.
