Synthesis of glycosaminoglycans (GAGs) by fibroblasts derived from sev
en patients with Down's syndrome, five patients with Edwards' syndrome
, and two patients with Patau's syndrome were studied in cell culture.
The aneuploid strains were compared with diploid fibroblasts from age
-matched controls. In terms of hyaluronic acid and sulfated CAG synthe
sis, the amount of synthesized hyaluronic acid was not significantly d
ifferent between postnatal aneuploid strains and controls.
