733418003: Joubert syndrome with Jeune asphyxiating thoracic dystrophy (disorder)

• SNOMED CT Concept\Clinical finding (finding)\...
• \Deformity (finding)\Deformity of limb (finding)\Longitudinal deficiency of limb\A short-rib dysplasia with characteristics of narrow thorax, short limbs and radiological skeletal abnormalities including "trident" aspect of the acetabula and metaphyseal changes. In rare cases, postaxial polydactyly may also be present. The narrow thorax may cause neonatal respiratory failure, and may be associated with persistent respiratory manifestations. The growth rate is variable but may be almost normal. Intellectual development is normal. The molecular basis of the syndrome has been partially elucidated indicating involvement of the IFT80 (3q25.33), DYNC2H1 (11q22.3), WDR19 (4p14) and TTC21B (2q24.3) genes, each encoding an intraflagellar transport protein. The syndrome is transmitted as an autosomal recessive trait.\A rare genetic developmental defect during embryogenesis characterized by the association of the classic features of Joubert syndrome (congenital midbrain-hindbrain malformations causing hypotonia, abnormal breathing and eye movements, ataxia and cognitive impairment) together with the skeletal anomalies of Jeune asphyxiating thoracic dystrophy (short ribs, long and narrow thorax causing respiratory failure, short-limbs, short stature, and polydactyly). Additional variable manifestations include cystic kidneys, liver fibrosis, and retinal dystrophy.

• \Disease\Disorder of limb (disorder)\Congenital anomaly of limb\Longitudinal deficiency of limb\A short-rib dysplasia with characteristics of narrow thorax, short limbs and radiological skeletal abnormalities including "trident" aspect of the acetabula and metaphyseal changes. In rare cases, postaxial polydactyly may also be present. The narrow thorax may cause neonatal respiratory failure, and may be associated with persistent respiratory manifestations. The growth rate is variable but may be almost normal. Intellectual development is normal. The molecular basis of the syndrome has been partially elucidated indicating involvement of the IFT80 (3q25.33), DYNC2H1 (11q22.3), WDR19 (4p14) and TTC21B (2q24.3) genes, each encoding an intraflagellar transport protein.
