Disorders for TPK1 Gene

(1) OMIM Diseases for TPK1 Gene (606370)


  • Thiamine metabolism dysfunction syndrome 5, episodic encephalopathy type (THMD5) [MIM:614458]: An autosomal recessive metabolic disorder due to an inborn error of thiamine metabolism. The phenotype is highly variable, but in general, affected individuals have onset in early childhood of acute encephalopathic episodes associated with increased serum and CSF lactate. These episodes result in progressive neurologic dysfunction manifest as gait disturbances, ataxia, dystonia, and spasticity, which in some cases may result in loss of ability to walk. Cognitive function is usually preserved, although mildly delayed development has been reported. These episodes are usually associated with infection and metabolic decompensation. Some patients may have recovery of some neurologic deficits. {ECO:0000269 PubMed:22152682}. Note=The disease is caused by mutations affecting the gene represented in this entry.
