OMIM® : ⁵⁷ Spondylo-megaepiphyseal-metaphyseal dysplasia is a rare autosomal recessive skeletal dysplasia characterized by disproportionate short stature with a short and stiff neck and trunk; relatively long limbs that may show flexion contractures of the distal joints; delayed and impaired ossification of the vertebral bodies and the presence of large epiphyseal ossification centers and wide growth plates in the long tubular bones; and numerous pseudoepiphyses of the short tubular bones in hands and feet (summary by Hellemans et al., 2009).

MalaCards based summary : Spondylo-Megaepiphyseal-Metaphyseal Dysplasia, also known as smmd, is related to metaphyseal dysplasia and cleidocranial dysplasia. An important gene associated with Spondylo-Megaepiphyseal-Metaphyseal Dysplasia is NKX3-2 (NK3 Homeobox 2). Affiliated tissues include bone, and related phenotypes are macrocephaly and short neck

KEGG : ³⁶ Spondylo-megaepiphyseal-metaphyseal dysplasia is a rare skeletal dysplasia. Its features are disproportionate short stature. On radiograph, defective ossification of vertebral bodies, enlarged epiphyses, and metaphyseal dysplasia are noted. It is inherited as an autosomal recessive trait.
