What is dicarboxylic aminoaciduria?

Dicarboxylic aminoaciduria is a rare metabolic disorder characterized by the excessive loss of aspartate and glutamate in urine. Symptoms have varied greatly among the few reported cases.[1][2] Dicarboxylic aminoaciduria is caused by mutations in the SLC1A1 gene. It is inherited in an autosomal recessive fashion.[2]
