摘要
Neurodegeneration with brain iron accumulation type 4 (NBIA4) also known as MPAN (mitochondria protein-associated neurodegeneration) is a rare neurological disorder which main feature is brain iron accumulation most frequently in the globus pallidus and substantia nigra. Whole exome sequencing (WES) in a 12-year-old patient revealed 2 variants in the C19orf12 gene, a previously reported common 11 bp deletion c.204_214del11, p.(Gly69Argfs*10) and a novel splicing variant c.193+5G>A. Functional analysis of novel variant showed skipping of the second exon, resulting in a formation of a truncated nonfunctional protein. This is the first functionally annotated pathogenic splicing variant in NBIA4.
