Congenitally short costocoracoid ligament- MedGen UID:

- Congenital Abnormality
A rare anomaly with characteristics of fixation of the scapula to the first rib, resulting in a cosmetic deformity with rounding of the shoulders and loss of the anterior clavicular contour. It has been described only once in several members of a single family from Canada. The abnormality resulted in a strong pectoral girdle with lack of mobility. Movements requiring rotation or retraction of the scapula were limited, but this does not normally interfere with daily activities.

- Disease or Syndrome
Greenberg dysplasia (GRBGD), also known as hydrops-ectopic calcification-moth-eaten (HEM) skeletal dysplasia, is a rare autosomal recessive osteochondrodysplasia characterized by gross fetal hydrops, severe shortening of all long bones with a moth-eaten radiographic appearance, platyspondyly, disorganization of chondroosseous calcification, and ectopic ossification centers. It is lethal in utero. Patient fibroblasts show increased levels of cholesta-8,14-dien-3-beta-ol, suggesting a defect of sterol metabolism (summary by Konstantinidou et al., 2008).
Herman (2003) reviewed the cholesterol biosynthetic pathway and 6 disorders involving enzyme defects in postsqualene cholesterol biosynthesis: Smith-Lemli-Opitz syndrome (SLOS; 270400), desmosterolosis (602398), X-linked dominant chondrodysplasia punctata (CDPX2; 302960), CHILD syndrome (308050), lathosterolosis (607330), and HEM skeletal dysplasia.
Tetraamelia syndrome 1- MedGen UID:

- •
- Disease or Syndrome
Tetraamelia syndrome-1 (TETAMS1) is characterized by complete limb agenesis without defects of scapulae or clavicles. Other features include bilateral cleft lip/palate, diaphragmatic defect with bilobar right lung, renal and adrenal agenesis, pelvic hypoplasia, and urogenital defects (Niemann et al., 2004).
Genetic Heterogeneity of tetraamelia syndrome
Tetraamelia syndrome-2 (TETAMS2; 618021) is caused by mutation in the RSPO2 gene (610575) on chromosome 8q23.
