B3GALT6 gene

beta-1,3-galactosyltransferase 6

The information on this page was automatically extracted from online scientific databases.

From NCBI 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.

From UniProt:

Beta-1,3-galactosyltransferase that transfers galactose from UDP-galactose to substrates with a terminal beta-linked galactose residue. Has a preference for galactose-beta-1,4-xylose that is found in the linker region of glycosaminoglycans, such as heparan sulfate and chondroitin sulfate. Has no activity towards substrates with terminal glucosamine or galactosamine residues.

  • Spondyloepimetaphyseal dysplasia with joint laxity

From UniProt:

Spondyloepimetaphyseal dysplasia with joint laxity, 1, with or without fractures (SEMDJL1): 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. [MIM:271640]

Ehlers-Danlos syndrome, spondylodysplastic type, 2 (EDSSPD2): A form of Ehlers-Danlos syndrome, a group of connective tissue disorders characterized by skin hyperextensibility, articular hypermobility, and tissue fragility. EDSSPD2 is an autosomal recessive form characterized by an aged appearance, developmental delay, short stature, craniofacial disproportion, generalized osteopenia, defective wound healing, hypermobile joints, hypotonic muscles, and loose but elastic skin.
