I aint sure of it .. but my best guess would be ... A) Defective Collagen formation ..
and the disease could be Menkes disease... !
Chondroitin Sulfate is defective in hurler syndrome .. (accumulates in this disease)

Although menkes is due to a Cu deficiency .. so on the second thought ... a DECREASEd Ceruloplasmin could be a possibility .. !
