Spondylo-Epi-Metaphyseal and Spondylo-Metaphyseal Dysplasias

This chapter further discusses bone dysplasias and explores achondrogenesis type 1A, odontochondrodysplasia, Schneckenbecken dysplasia, opsismodysplasia, spondylometaphyseal dysplasia (Sedaghatian type), spondyloenchondrodysplasia, SEMD (PAPSS2 type) and brachyolmia (autosomal recessive type), Dyggve-Melchior-Clausen dysplasia, spondylometaepiphyseal dysplasia (short limb-abnormal calcification type), spondylometaphyseal dysplasia with cone-rod dystrophy, dyssegmental dysplasia, Schwartz-Jampel syndrome, spondyloepiphyseal dysplasia tarda (X-linked), aggrecan-associated skeletal dysplasias, Wolcott-Rallison syndrome, Schimke immunoosseous dysplasia, progressive pseudorheumatoid chondrodysplasia, spondylometaphyseal dysplasia (corner fracture type), sponastrime dysplasia, CODAS syndrome, N-acetyl-neuraminic acid synthase (NANS) deficiency, and spondylo-epi-metaphyseal dysplasia with immune deficiency and developmental disability (EXTL3-deficient type). Each discussion includes major radiographic features, major clinical findings, genetics, major differential diagnoses, and a bibliography.
