Neurodegeneration with brain iron accumulation-4 (NBIA4) is a neurodegenerative disorder characterized by progressive spastic paraplegia, parkinsonism unresponsive to L-DOPA treatment, and psychiatric or behavioral symptoms. Other neurologic features, including optic atrophy, eye movement abnormalities, dystonia, dysphagia, dysarthria, and motor axonal neuropathy, may occur. Brain MRI shows T2-weighted hypointensities in the globus pallidus and substantia nigra. Onset is usually in the first 2 decades, but later onset has been reported (summary by Dogu et al., 2013). There is phenotypic variation: some patients may not have extrapyramidal signs and may have muscle weakness and atrophy as well as cognitive impairment or developmental delay (Deschauer et al., 2012). Both autosomal recessive and autosomal dominant inheritance have been reported (see INHERITANCE and MOLECULAR GENETICS).
For a general phenotypic description and a discussion of genetic heterogeneity of NBIA, see NBIA1 (234200). (614298)
MalaCards based summary : Neurodegeneration with Brain Iron Accumulation 4, also known as nbia4, is related to spastic paraplegia 43, autosomal recessive and movement disease, and has symptoms including ataxia, tremor and abnormality of extrapyramidal motor function. An important gene associated with Neurodegeneration with Brain Iron Accumulation 4 is C19orf12 (Chromosome 19 Open Reading Frame 12), and among its related pathways/superpathways is Pantothenate and CoA biosynthesis. Affiliated tissues include brain, eye and globus pallidus, and related phenotypes are global developmental delay and cerebellar atrophy Disease Ontology : 12 A neurodegeneration with brain iron accumulation that has material basis in autosomal recessive inheritance of mutation in the C19orf12 gene on chromosome 19q12. UniProtKB/Swiss-Prot : 73 Neurodegeneration with brain iron accumulation 4: A neurodegenerative disorder associated with iron accumulation in the brain, primarily in the basal ganglia. NBIA4 results in speech difficulty, extrapyramidal signs, oromandibular and generalized dystonia, and parkinsonism. Most patients have progressive involvement of the corticospinal tract, with spasticity, hyperreflexia, and extensor plantar responses. |
