Adult-Onset Fatal Neurohepatopathy in a Woman Caused by MPV17 Mutation.

ABSTRACT: Hepatocerebral mitochondrial DNA depletion syndromes are classically considered diseases of early childhood, typically affecting the liver, peripheral, and central nervous systems with a rapidly progressive course. Evidence is emerging that initial symptom onset can extend into adulthood, though few such cases have been reported. We describe a 25-year-old woman who presented initially with secondary amenorrhea, followed by a megaloblastic anemia, lactic acidosis, leukoencephalopathy, progressive peripheral neuropathy, and liver cirrhosis. An apparently homozygous P98L mutation was identified in MPV17, a gene associated with a lethal infantile neurohepatopathy. Homozygosity for the same allele was recently reported in a man with a similar hepatic and neurologic phenotype. This is the first
