Etiology
They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]
Etiology Different causal homozygous mutations of the NAGA gene (22q13.2) have been described in the reported patients. These mutations lead to the dysfunction, instability and rapid degradation of the lysosomal protein, NAGA. [rarediseases.info.nih.gov]
