Summaries for B3GALT6 Gene

Entrez Gene Summary for B3GALT6 Gene

  • The enzyme encoded by this intronless gene is a beta-1,3-galactosyltransferase found in the medial Golgi apparatus, where it catalyzes the transfer of galactose from UDP-galactose to substrates containing a terminal beta-linked galactose moiety. The encoded enzyme has a particular affinity for galactose-beta-1,4-xylose found in the linker region of glycosamines. This enzyme is required for glycosaminoglycan synthesis. [provided by RefSeq, Jun 2013]

GeneCards Summary for B3GALT6 Gene

B3GALT6 (UDP-Gal:BetaGal Beta 1,3-Galactosyltransferase Polypeptide 6) is a Protein Coding gene. Diseases associated with B3GALT6 include spondyloepimetaphyseal dysplasia with joint laxity, type 1, with or without fractures and ehlers-danlos syndrome, progeroid type, 2.

Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Spondyloepimetaphyseal dysplasia with joint laxity, 1, with or without fractures (SEMDJL1) [MIM:271640]: A bone disease 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. Additional skeletal features include 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. {ECO:0000269 PubMed:23664117, ECO:0000269 PubMed:23664118}.
