(From Uniprot)
May play an important role in fibrillogenesis by controlling lateral growth of collagen II fibrils.
Gene References into Functions
  1. results suggested that common polymorphisms in these two candidate genes were unlikely to play major roles in the genetic susceptibility to HM. Nevertheless, to avoid filtering real myopia genes, the role of COL11A1 and COL18A1 in the pathogenesis of myopia requires more refinement in both animal models and human genetic epidemiological studies PMID: 29781737
  2. These results showed that the frequency distribution of genotypes of the rs2229783 polymorphism in COL11A1 was significantly different between the Kashin-Beck Disease (KBD) and control groups; the expression level of COL11A in cartilage was significantly lower in the KBD group, but no association was found between the rs2229783 and the severity of KBD. PMID: 29773097
  3. We confirmed that the rs1676486 of COL11A may be functionally associated with lumbar disc herniation (LDH) in the Chinese population. Extracellular matrix related proteins may play an important role in the pathogenesis of LDH. Our findings shed light on a better understanding of the pathogenesis of LDH, which could be a promising target for a novel treatment modality of LDH. PMID: 29321344
  4. Study found one gene significantly associated when looking for associations between multiple common and rare variants with pneumococcal meningitis susceptibility, namely the COL11A1 gene. PMID: 27389768
  5. The SNPs rs1337185 in COL11A1 and rs162509 in ADAMTS5 are associated with susceptibility to lumbar disc degeneration. The C allele of rs1337185 is risky for patients who are affected by lumbar pathologies such as disc herniation, stenosis and spondylolisthesis. The G allele of rs16250 represents a risk factor for the development of disc herniation. PMID: 28583914

  10. the racial differences of COL11A1 were consistent across multiple molecular levels, with higher mutation frequency, higher methylation, and lower expression in White patients. This indicated that COL11A1 might play important roles in ESCC, especially in White population. Additional studies are needed to further explore their functions in esophageal cancer PMID: 28393072
  11. Investigated genetic variants in COL11A1 predisposing to primary hip OA in Han Chinese individuals.Two SNPs (rs1241164 and rs4907986) were found to be significantly associated with hip OA risk (adjusted p = 0.000731 and 0.000477). An increased risk of OA was associated with possession of the C allele of rs1241164 and the T allele of rs4907986. PMID: 27936936
  12. COL11A1 antibody can assist in distinguishing the cancer-associated desmoplastic stroma from that associated with misplaced adenomatous mucosa.

However, COL11A1 has limited value in diagnosing superfically invasive carcinomas with very little desmoplastic stroma. PMID: 27021528
