dc.description.abstract | Phospholipase A2 group VI (PLA2G6)-associated neurodegeneration (PLAN) is an autosomal recessive neurodegenerative disease with a wide clinical spectrum; however, the genotype-phenotype correlation is unknown. Here, we report different phenotypes in one family with the same genotype. A 28-year-old male presented with slowly progressive gait disturbance with spasticity. Onset occurred at 11 years. Interestingly, his younger brother, a 24-year-old male, presented with progressive Parkinsonism, which began at 22 years. He showed excellent response to levodopa but developed a fluctuating medication response and levodopa-induced dyskinesia 1. year after starting levodopa medication. He also demonstrated hyperreflexia, but no spasticity. Dopamine transporter imaging showed reduced uptake in the bilateral putamen. In whole-exome sequencing and Sanger sequencing, a homozygous pathogenic variant (p. R747W) in the PLA2G6 gene was detected in both cases. Despite different clinical features, both subjects had hyperreflexia during the examination and claval hypertrophy was shown on the brain magnetic resonance imaging. | - |
