  • Additional terms used to describe the segment of the limb with the greatest involvement are rhizomelic (proximal), mesomelic (middle), and acromelic (distal). (medscape.com)
  • In diastrophic dysplasia, the extremity involvement is rhizomelic (in 40% of cases) or mesomelic (in 29% of cases). (medscape.com)

  • One of the many factors contributing to the formation of non-genetic forms of arthrogryposis in humans are intrauterine infections (IUI), in particular viral etiology. (clinlabdia.ru)
  • PEX1, also known as Peroxisome biogenesis factor 1, is a 1,283 amino acid protein that is 143 kDa, cytoplasmic but is often anchored to a peroxisomal membrane where it forms a heteromeric complex and plays a role in the import of proteins into peroxisomes and peroxisome biogenesis.

  • Achondroplasia is the most common form of disproportionate short stature and occurs in 1 in 20,000 live births. (medscape.com)
  • WD40 repeats usually assume a 7-8 bladed beta-propeller fold, but proteins have been found with 4 to 16 repeated units, which also form a circularised beta-propeller structure. (embl.de)
  • It is very likely that all WD-repeat proteins form a similar structure. (embl.de)
