Dwarfism Associated with Normal Serum Growth Hormone and Increased Bioassayable, Receptorassayable, and Immunoassayable Somatomedin

Abstract
An adolescent male is described with growth failure, normal growth hormone and elevated somatomedin by bioassay, radioreceptorassay and radioimmunoassay. A previously unrecognized defect in somatomedin responsiveness is suspected.
