Presentation
Unlike the previously described phenotype, Patient 2 presented with a Leigh syndrome like non-episodic early-onset global developmental delay, thus extending the phenotypic spectrum of the disorder. [push-zb.helmholtz-muenchen.de]
We present evidence suggesting that thiamine supplementation may rescue TPK enzyme activity. [escholar.manchester.ac.uk]
Lactic acidosis and 2-ketoglutaric aciduria appear to be markers of this disorder, although they do not seem to have been present in all cases. [ommbidblog.com]

Patients: We present a sibling pair with Leighs disease, progressive hypotonia, regression, and chronic encephalopathy. Whole exome sequencing in the younger sibling demonstrated homozygous TPK1 mutations. [ashg.org]
