Description : Spondyloepimetaphyseal dysplasia with joint laxity type 1 (SEMDJL1) is characterized
by vertebral abnormalities and ligamentous laxity that result in spinal misalignment
and progressive severe kyphoscoliosis, thoracic asymmetry, and respiratory compromise
resulting in early death. Nonaxial skeletal involvement includes elbow deformities
with radial head dislocation, dislocated hips, clubfeet, and tapered fingers with
spatulate distal phalanges. Many affected children have an oval face, flat midface,
prominent eyes with blue sclerae, and a long philtrum. Palatal abnormalities and congenital
heart disease are also observed (summary by Smith et al., 1999). Patients with a similar
phenotype and fractures have been described (Malfait et al., 2013).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the UDP-Gal:beta-Gal beta-1,3-galactosyltransferase polypeptide
6 gene (B3GALT6, 615291.0001);
