Description

Fibrochondrogenesis is a rare congenital disorder characterised by distinctive facial features and skeletal abnormalities. Affected individuals have shortened long bones with dumbbell shaped ends, flattened vertebral bodies, underdeveloped pelvic bones and a narrow chest. Fibrochondrogenesis is neonatally lethal and in those patients who survive infancy, auditory and ocular defects have been observed. Compound heterozygous mutation in the COL11A1 gene is known to cause fibrochondrogenesis 1.

Other Reports

Arab

Al-Gazali et al. (2003) conducted a 5-year prospective study in newborns at Al Ain Medical District to determine the pattern and prevalence of different types of osteochondrodysplasias in the United Arab Emirates. Fibrochondrogenesis was found to be the most common type of recessive skeletal dysplasia within the study group. Four cases were identified among the 38,048 births during the study period.

Lebanon

Megarbane et al. (1998) reported fibrochondrogenesis in an infant whose parents were consanguineous. The prenatal ultrasonography performed during second trimester revealed intrauterine growth retardation and the child died two hours post delivery due to respiratory distress. Prior to this case, another child born to the same couple reportedly had similar symptoms, and died 30 minutes after delivery.

Oman

Al-Gazali et al. (1997) reported the first case of fibrochondrogenesis in an Arab patient. The patient, an Omani child whose parents were consanguineous, was prenatally diagnosed with short limbs in the third trimester. A second case of fibrochondrogenesis was reported later in the same family by Al-Gazali et al. (1999).
