" /> Spondylocostal dysostosis 1, autosomal recessive - CISMeF





Preferred Label : Spondylocostal dysostosis 1, autosomal recessive;

Symbol : SCDO1;

CISMeF acronym : SCDO1;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Spondylothoracic dysostosis; Spondylothoracic dysplasia; Jarcho-levin syndrome; Vertebral anomalies; Costovertebral dysplasia;

Description : The spondylocostal dysostoses are a heterogeneous group of axial skeletal disorders characterized by multiple segmentation defects of the vertebrae (SDV), malalignment of the ribs with variable points of intercostal fusion, and often a reduction in rib number. The term 'spondylocostal dysostosis' is best applied to those phenotypes with generalized SDV and a broadly symmetric thoracic cage (summary by Gucev et al., 2010). - Genetic Heterogeneity Other forms of autosomal recessive SCDO include SCDO2 (608681), caused by mutation in the MESP2 gene (605195) on chromosome 15q26.1; SCDO3 (609813), caused by mutation in the LFNG gene (602576) on chromosome 7p22; and SCDO4 (613686), caused by mutation in the HES7 gene on chromosome 17p13.2. An autosomal dominant form of SCDO has also been described (SCDO5; 122600).;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the delta like canonical Notch ligand 3 gene (DLL3, 602768.0001);

Prefixed ID : #277300;
