Summaries for Smith-Mccort Dysplasia 1

NIH Rare Diseases : 54 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 178355Disease definitionSmith-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.Visit the Orphanet disease page for more resources.

MalaCards based summary : Smith-Mccort Dysplasia 1, also known as smith-mccort dysplasia, is related to dyggve-melchior-clausen disease and smith-mccort dysplasia 2, and has symptoms including waddling gait An important gene associated with Smith-Mccort Dysplasia 1 is DYM (Dymeclin). Affiliated tissues include spinal cord, bone and t cells, and related phenotypes are genu valgum and scoliosis

Disease Ontology : 12 A Syggve-Melchior-Clausen disease characterized by short limbs and a short trunk with a barrel-shaped chest and has material basis in homozygous or compound heterozygous mutation in the DYM gene on chromosome 18q.

OMIM : 58 Smith-McCort dysplasia is a rare autosomal recessive osteochondrodysplasia characterized by short limbs and trunk with barrel-shaped chest. The radiographic phenotype includes platyspondyly, generalized abnormalities of the epiphyses and metaphyses, and a distinctive lacy appearance of the iliac crest, features identical to those of Dyggve-Melchior-Clausen disease. Spinal cord compression due to atlantoaxial instability occurs in both SMC and DMC (Spranger et al., 1976; Nakamura et al., 1997). (607326)

UniProtKB/Swiss-Prot : 76 Smith-McCort dysplasia 1: A rare autosomal recessive osteochondrodysplasia with skeletal features identical to those of Dyggve-Melchior-Clausen syndrome, but with normal intelligence and no microcephaly. It is characterized by short limbs and trunk with barrel-shaped chest. The radiographic phenotype includes platyspondyly, generalized abnormalities of the epiphyses and metaphyses, and a distinctive lacy appearance of the iliac crest.
