Lauren Thomas (VIctorian Clinical Genetics Services)

Green List (high evidence)

Over 10 families reported with an autosomal recessive neurologic disorder characterised by global developmental delay apparent from early infancy, poor overall growth often with microcephaly (6/10), impaired intellectual development with delayed or absent speech, axial hypotonia, and peripheral spasticity. Additional common but variable features include early-onset seizures, optic atrophy with poor visual fixation, and dysmorphic facial features. Brain imaging shows cerebral atrophy, poor or absent myelination with loss of white matter volume, and often hypoplasia of the corpus callosum and/or cerebellum.
