Sarcosinemia (SAR) also called hypersarcosinemia and SARDH deficiency is a rare autosomal recessive metabolic disorder characterized by an increased concentration of sarcosine in blood plasma and urine (sarcosinuria). It can result from an inborn error of sarcosine metabolism or from severe folate deficiency related to the folate requirement for the conversion of sarcosine to glycine. It is thought to be a relatively benign condition.
