摘要: Beta-propeller protein-associated neurodegeneration (BPAN), also known as static encephalopathy of childhood with in adulthood (SENDA), is a subtype brain iron accumulation (NBIA). BPAN caused by mutations an X-linked gene WDR45 that involved autophagy. characterized developmental delay or intellectual disability until adolescence early adulthood, followed severe dystonia, parkinsonism, and progressive dementia. Brain magnetic resonance imaging (MRI) shows deposition the bilateral globus pallidus (GP) substantia nigra (SN). Clinical manifestations laboratory findings are limited. We report 3-year-old girl who presented characteristic facial features. In addition to chronic elevation serum aspartate transaminase, lactate dehydrogenase, creatine kinase, soluble interleukin-2 receptor, she had persistent neuron specific enolase (NSE) cerebrospinal fluid. MRI using susceptibility-weighted (SWI) demonstrated GP SN bilaterally. Targeted next-generation sequencing identified de novo splice-site mutation, c.831-1G>C WDR45, which resulted aberrant splicing evidenced reverse transcriptase-PCR. Persistent NSE on SWI may provide clues for diagnosis childhood.
