Hypercatabolic hypoproteinemia is an autosomal recessive disorder caused by mutations of the B2M gene that encodes for beta-2 microglobulin. Laboratory findings unclude low albumin and immunoglobulin levels caused by an increased turnover. The disease is associated with diabetes and skeletal deformations.
