Renal carnitine transport defect
An autosomal recessive inherited disorder caused by mutations in the slc22a5 gene.

This abnormality results in reduced energy production and accumulation of fatty acids in the tissues. Clinical manifestations of confusion, muscle weakness, hypoglycemia, encephalopathy and cardiomyopathy may be exacerbated during fasting.
