Proprotein convertase 1/3 (PC1/3) deficiency is a rare autosomal recessive disorder caused by mutations in the PCSK1 gene. It is associated with early-onset obesity, severe malabsorptive diarrhea, certain endocrine abnormalities, and dysregulation of glucose homeostasis. PC1/3 is an endoprotease that processes many prohormones expressed in endocrine and neuronal cells.
