Feb 5th, 2021 - Biallelic 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 se...

Dec 6th, 2017 - Amish lethal microcephaly is characterized by severe congenital microcephaly and highly elevated 2-ketoglutarate or lactic acidosis. The occipitofrontal circumference is typically more than two standard deviations (occasionally >6 SD) below the me...

Sep 11th, 2013 - Mammalian cells obtain vitamin B1 (thiamin) from their surrounding environment and convert it to thiamin pyrophosphate (TPP) in the cytoplasm. Most of TPP is then transported into the mitochondria via a carrier-mediated process that involves the m...
