Rare cause of ketolysis: Monocarboxylate transporter 1 deficiency

Background. Monocarboxylate transporter 1 (MCT1) deficiency (MIM #616095) is a relatively new identified cause of recurrent ketoacidosis triggered by fasting or infections. MCT1 was first described in 2014 by van Hasselt et al. to result from both homozygous and heterozygous mutations in the...

description Background. Monocarboxylate transporter 1 (MCT1) deficiency (MIM #616095) is a relatively new identified cause of recurrent ketoacidosis triggered by fasting or infections. MCT1 was first described in 2014 by van Hasselt et al. to result from both homozygous and heterozygous mutations in the SLC16A1 gene. Patients with homozygous mutations are known to have a more severe phenotype with developmental delay and epilepsy. Thirteen patients with MCT1 deficiency with ketoacidosis have been reported in the literature to date. Case. We describe a developmentally normal male patient with heterozygous missense variation in the SLC16A1 gene. Our patient who presented with cyclic vomiting and ketoacidosis episodes was found to have a heterozygous c.303T > G (p.Ile101Met) missense mutation. Conclusions. It is crucial to take early preventive measures and to minimize the harmful effects of ketoacidotic episodes. MCT1 deficiency should be considered in the differential diagnosis of ketoacidosis in patients with normal SCOT and ACAT1 activities.
