Abstract Background SLC25A19 gene mutations cause Amish congenital lethal microcephaly and bilateral striatal necrosis with polyneuropathy. We are reporting two cases of bilateral striatal necrosis with polyneuropathy due to SLC25A19 gene mutations. Methods A 36-month-old boy and a 5-year-old girl, unrelated, presented with recurrent episodes of flaccid paralysis and encephalopathy following nonspecific febrile illness. Examination showed dystonia and absent deep tendon reflexes. Results Nerve conduction studies showed an axonal polyneuropathy. Magnetic resonance imaging (MRI) of the brain in both cases showed signal changes in the basal ganglia. Next-generation sequencing revealed a novel homozygous missense variation c.910G>A (p.Glu304Lys) in the SLC25A19 gene in the boy and a homozygous mutation c.869T > A (p. Leu290Gln) in the SLC25A19 gene in the girl. Mutations were validated by Sanger sequencing, and carrier statuses of parents of both children were confirmed. Both children improved with thiamine supplementation. Conclusion If any child presents with recurrent encephalopathy with flaccid paralysis, dystonia, and neuropathy, a diagnosis of bilateral striatal necrosis with polyneuropathy due to SLC25A19 mutations should be considered and thiamine should be initiated.

AbstractObjectivesBiallelic mutations in the SLC25A19 gene impair the function of the thiamine mitochondrial carrier, leading to two distinct clinical phenotypes. Homozygosity for the c.530G > C mutation is invariably associated to Amish lethal microcephaly. The second phenotype, reported only in 8 patients homozygous for different non-Amish mutations (c.373G > A, c.580T > C, c.910G > A, c.869T > A, c.576G > C), is characterized by bilateral striatal necrosis and peripheral polyneuropathy. We report a new patient with the non-Amish SLC25A19 phenotype showing compound heterozygosity for the new variant c.673G > A and the known mutation c.373G > A.Case presentationThe natural history of non-Amish SLC25A19 deficiency is characterized by acute episodes of fever-induced encephalopathy accompanied by isolated lactic acidosis and Leigh-like features at magnetic resonance imaging (MRI). Acute episodes are prevented by high-dose thiamine treatment (600 mg/day). As shown in the new case, both mild clinical signs and basal ganglia involvement can precede the acute encephalopathic onset of the disease, potentially allowing treatment anticipation and prevention of acute brain damage. Peripheral axonal neuropathy, observed in 7 out of 9 patients, is not improved by thiamine therapy. In two early treated patients, however, peripheral neuropathy did not occur even on long-term follow-up, suggesting a potential preventive role of treatment anticipation also at the peripheral level.ConclusionsNon-Amish SLC25A19 deficiency is an extra-rare cause of Leigh syndrome responsive to thiamine treatment. Ex adiuvantibus thiamine treatment is mandatory in any patient with Leigh-like features.
