Clinical summary

Help

Imported from OMIM

Fibrochondrogenesis is a severe, autosomal recessive, short-limbed skeletal dysplasia clinically characterized by a flat midface with a small nose and anteverted nares, significant shortening of all limb segments but relatively normal hands and feet, and a small bell-shaped thorax with a protuberant abdomen. Radiographically, the long bones are short and have broad metaphyseal ends, giving them a dumb-bell shape. The vertebral bodies are flat and, on lateral view, have a distinctive pinched appearance, with a hypoplastic posterior end and a rounded anterior end. The ribs are typically short and wide and have metaphyseal cupping at both ends (summary by Tompson et al., 2010). Genetic Heterogeneity of Fibrochondrogenesis Fibrochondrogenesis-2 (FBCG2; 614524) is caused by mutation in the COL11A2 gene (120290) on chromosome 6p21.3.
