Zellweger Syndrome

Definition: An autosomal recessive peroxisomal disorder that typically presents in the neonatal period and is usually fatal. Clinical features include hypotonia, dysmorphic skull and facial bones, visual compromise, multifocal seizures, hepatomegaly, biliary dysgenesis, and swallowing difficulties. Pathologically, there are migration deficits of the neocortex and degeneration of white matter tracts. Zellweger-like syndrome refers to conditions that phenotypically resemble neonatal Zellweger syndrome, but occur in childhood or adulthood (From Adams et al., Principles of Neurology, 6th ed, p946)

Zygomycosis

Definition: Infection in humans and animals caused by fungi in the class Zygomycetes. It includes MUCORMYCOSIS and entomophthoramycosis.

Phycomycosis, closely related to zygomycosis, describes infection with members of Phycomycetes, an obsolete classification.
Annotation: fungus dis caused by various Zygomycetes; for dis caused by Mucorales, MUCORMYCOSIS is available
