摘要: Abstract Neurodegeneration with brain iron accumulation (NBIA) is a genetically heterogeneous disorder, characterized by the of in regions such as basal ganglia. We enrolled 28 patients childhood intellectual disability and young-onset parkinsonism (≤40 years at onset) 4 infantile neuroaxonal dystrophy. All had been clinically diagnosed, prevalence genetic mutations linked to NBIA ( PANK2 [exons 1–7], PLA2G6 2–17], C19orf12 1–3], WDR45 2–11], COASY 1–9], FA2H RAB39B 1, 2]) was evaluated. detected 7 female (25.0%, 28) de novo heterozygote mutations, which are known be pathogenic for beta-propeller protein-associated neurodegeneration. common clinical features. Pathogenic other genes were not found. also screened 98 early-onset without 110 normal controls Japanese origin mutations. None Our data suggest high frequency neurodegeneration population.
