ORPHA:178355· ICD-10 Q77.7· Smith-McCort dysplasia

Визначення(English summary)

Smith-McCort dysplasia (SMC) is a rare spondylo-epi-metaphyseal dysplasia characterized by the clinical manifestations of coarse facies, short neck, short trunk dwarfism with barrel-shaped chest and rhizomelic limb shortening, as well as specific radiological features (i.e. generalized platyspondyly with double-humped vertebral end plates and iliac crests with a lace-like appearance) and normal intelligence. The clinical and skeletal features are similar to those seen in the allelic disorder Dyggve-Melchior-Clausen syndrome (DMC; see this term), but can be distinguished from this syndrome by the absence of intellectual deficiency and microcephaly in SMC.
