In the present review, we have discussed clinical spectrum, genetics and signalopathies of isolated acromesomelic dysplasias. Copyright © 2016 Elsevier Masson SAS. All rights reserved. [ncbi.nlm.nih.gov]

The study presented here investigated three consanguineous families (A, B, C) segregating AMDM in an autosomal recessive manner. Linkage in the families was established to the NPR2 gene on chromosome 9p12-21. [wwww.unboundmedicine.com]

In AMDM all skeletal elements are present but show abnormal rates of linear growth. Acronym AMDM Synonyms St. [uniprot.org]

• Disproportionate Short Stature

  Abstract Acromesomelic dysplasia Maroteaux type (AMDM) is an autosomal recessive skeletal disorder characterized by disproportionate short stature with shortening of the acromesomelic sections of the limbs. [ncbi.nlm.nih.gov]

  short stature ; Flared metaphysis ; Frontal bossing ; Hypoplasia of the radius ; Joint laxity ; Limited elbow extension ; Long hallux ; Lower thoracic kyphosis ; Lumbar hyperlordosis ; Ovoid vertebral bodies ; Prominent forehead ; Radial bowing ; Redundant [mousephenotype.org]

• Turkish

  However, linkage analyses in four consanguineous AMDM families of Turkish and Lebanese ancestry supported the mapping of a gene for typical AMDM to chromosome 9p13-q12 (Zmax=3.27 and Zmax=3.23 at θ=0 at loci D9S1878 and D9S1817 respectively). [jmg.bmj.com]

• Short Hands

  Acromelia is the shortening of the bones of the hands and feet. Thus, the short stature of affected individuals is the result of unusually short forearms and abnormal shortening of bones of the lower legs. [metrohealth.net]

  The hands and feet appear unusually short and broad at birth. [rarediseases.org]

• Disproportionate Dwarfism

  Mutations in the gene NPR2 have been shown to cause acromesomelic dysplasia-type Maroteaux (AMDM), an autosomal recessive skeletal disproportionate dwarfism disorder in humans. [paperity.org]

  Although other groups may extend the criteria for certain forms of dwarfism to 5 feet, the average height of an adult with dwarfism is 4 feet. There are two main categories of dwarfism -- disproportionate and proportionate. [webmd.com]

• Long Arm

  Each chromosome has a short arm designated “p” and a long arm designated “q”. Chromosomes are further sub-divided into many bands that are numbered. [rarediseases.org]

• Decrease in Height

  The skull is dolichocephalic and a shortness of the trunk, with decreased vertebral height and narrowing of the lumbar interpedicular distances, is consistently observed. [jmg.bmj.com]

• Suggestibility

  This study suggests that genetic heterogeneity accounts for the variable clinical and radiological severity of AMDM. [ncbi.nlm.nih.gov]

  The presence of the same mutation (p.T907M) and haplotype in five families (A, B, C, D, E) is suggestive of a founder effect. [paperity.org]

  It is worth remembering that the existence of mild AMDM was suggested by Borrelli et al, 14 who described a boy moderately affected with AMDM with a birth length of 50 cm and a growth pattern of −2.6 SD at the age of 2½ years. [jmg.bmj.com]

  The findings enlisted here suggest that early preventive measures and intercepting any developing malocclusions would suffice the promotion of good oral health during infancy and childhood. [ Fehan Ahmed Khan, Gaurav Kumar Mittal, Adnan Ahmed, Deepanshu [journalijar.com]

Standard Therapies Treatment The treatment of acromesomelic dysplasia is directed toward the specific symptoms and physical characteristics that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists. [rarediseases.org]

Early diagnosis and treatment can help prevent or lessen some of the problems associated with dwarfism. [webmd.com]
