Abstract

OBJECTIVE: To examine the genotype to phenotype connection in glucose transporter type 1 (GLUT1) deficiency and whether a simple functional assay can predict disease outcome from genetic sequence alone.

METHODS: GLUT1 deficiency, due to mutations in

RESULTS: Disease severity inversely correlated with rate of glucose transport between control (V

CONCLUSIONS: Disease severity can be partly explained by the extent of GLUT1 dysfunction. This simple
