Insulin receptor evaluation in congenital generalized lipodystrophy. Case report of an infant.
Insulin specific receptors on red blood cells and cultured fibroblasts were investigated in a male infant affected of congenital generalized lipodystrophy (CGL). Total insulin binding capacity appeared mildly reduced, with apparently selective involvement of the high-affinity receptors on red blood cells but not on fibroblasts. Such alterations did not produce any impairment of glucose metabolism.
