Dicarboxylic aminoaciduria

Is it possible to reach late adolescence with undiagnosed dicarboxylic aminoaciduria?

Currently, there is no wide screening done for dicarboxylic aminoaciduria, and there are few clinical symptoms that would prompt a clinician to consider a diagnosis of this rare disorder. As a result, it is possible that children as well as adults could have dicarboxylic aminoaciduria without knowing it. Since the actual prevalence of the disorder is not known, it is difficult to calculate the likelihood that any one individual might have it.
