Summary

Excerpted from the GeneReview: SLC25A19-Related Thiamine Metabolism Dysfunction
SLC25A19-related thiamine metabolism dysfunction (SLC25A19 deficiency) is characterized by two phenotypes: Amish lethal microcephaly and thiamine metabolism dysfunction syndrome 4 (THMD-4). Amish lethal microcephaly is characterized by severe congenital microcephaly, developmental delay, seizures, 2-oxoglutaric aciduria, and often premature death. THMD-4 is characterized by febrile illness-associated episodic encephalopathy, progressive polyneuropathy, and bilateral striatal necrosis.
