Novel C19orf12 loss-of-function variant leading to neurodegeneration with brain iron accumulation

Abstract

Neurodegeneration with brain iron accumulation (NBIA) is a group of inherited disorders characterised by cerebral iron overload mainly in the basal ganglia. Mitochondrial membrane protein-associated neurodegeneration (MPAN) is a form of NBIA caused by pathogenic C19orf12 gene variants. We report on a Romanian patient with MPAN confirmed through exome sequencing, revealing a homozygous nonsense variant in the C19orf12 gene, NM_001031726.3: c.215T>G (p.Leu72*), that co-segregates with disease in tested relatives: the patient`s parents, younger brother and paternal uncle are heterozygous carriers. This is a novel disease-causing variant in the C19orf12 gene and the first reported MPAN case in a Romanian patient.

Keywords: C19orf12; mitochondrial membrane protein-associated neurodegeneration; neurodegeneration with brain iron accumulation.
