  1. Results show that absence of Col (show HDAC1 Proteins) IX induces early developmental, structural and biomechanical alterations in both vertebral body and intervertebral disc which eventually cause severe degenerative changes in the aging spine.

  1. Here, we describe the first autosomal recessive Stickler family due to loss of function mutations (c.1176_1198del, p.Gln393Cysfs*25) of COL9A3 gene. These findings extend further the role of collagen genes family in the disease pathogenesis.

  2. The allelic variants in the collagen IX genes - COL9A2 and COL9A3 have been identified as genetic risk factors for intervertebral disc disease--{review}

  3. The NC2 (show GTF2H5 Proteins) domain of type IX collagen determines the chain composition but also the chain register of the triple helix.

  4. Studies indicate that two SNPs that introduce tryptophan polymorphisms in COL9A2 and COL9A3 are independently linked to an increased risk of lumbar disc disease.

  5. We report an 81% mutation detection rate for pseudoachondroplasia, of which COMP (show COMP Proteins)+Col9A3 mutations were more prevalent (61%) than COMP (show COMP Proteins) mutations alone (30%).

  6. Both Trp2 (show DCT Proteins) and Trp3 (show TRPC3 Proteins) allelic products are incorporated into cross-linked fibrillar network of developing human cartilage apparently normally. Any pathological consequences are likely to be long-term and indirect rather than from overt misassembly of matrix.

  7. Patients with COL9A3 in-frame deletion of three amino acid residues (G181-P183 del) and missense mutation (D617E) showed moderate progressive bilateral sensorineural hearing impairment in all frequencies.

  8. a fragment of collagen type IX alpha chain (show FCGRT Proteins) is found in 34% of newborns with ureteropelvic junction obstruction, and in 100% of normals.

COL9A3 Protein Profile

Protein Summary

This gene encodes one of the three alpha chains of type IX collagen, the major collagen component of hyaline cartilage. Type IX collagen, a heterotrimeric molecule, is usually found in tissues containing type II collagen, a fibrillar collagen. Mutations in this gene are associated with multiple epiphyseal dysplasia type 3.
