Abstract
Creatine deficiency syndromes are congenital metabolic diseases characterized by decreased cerebral creatine levels as a result of disorders in creatine synthesis and transport. Therefore, magnetic resonance spectroscopy is a valuable tool for diagnosis. This disease can be explained by congenital disorders occurring in three forms at different stages of the creatine metabolic pathway. Two of disorders arise autosomal recessively in creatine biosynthesis, arginine-glycine amidinotransferase, and guanidinoacetate methyltransferase enzyme deficiency. The third disorder occurs as a result of an SLC6A8 variant in the form of creatine carrier protein deficiency. In this article, a patient with SLC6A8 carrier deficiency is presented.
