Preferred Label : Fibrochondrogenesis 1;
Symbol : FBCG1;
CISMeF acronym : FBCG1;
Type : Phenotype, molecular basis known;
Description : 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.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the collagen XI, alpha-1 polypeptide gene (COL11A1, 120280.0008);
Laboratory abnormalities : Disorganized growth plate cartilage;
Prefixed ID : #228520;
