Summaries for COL9A3 Gene

Entrez Gene Summary for COL9A3 Gene

  • 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. [provided by RefSeq, Jan 2010]

GeneCards Summary for COL9A3 Gene

COL9A3 (Collagen Type IX Alpha 3 Chain) is a Protein Coding gene. Diseases associated with COL9A3 include Epiphyseal Dysplasia, Multiple, 3 and Intervertebral Disc Disease. Among its related pathways are Integrin Pathway and ERK Signaling. Gene Ontology (GO) annotations related to this gene include extracellular matrix structural constituent conferring tensile strength. An important paralog of this gene is COL9A2.

  • Intervertebral disc disease (IDD) [MIM:603932]: A common musculo-skeletal disorder caused by degeneration of intervertebral disks of the lumbar spine. It results in low-back pain and unilateral leg pain. {ECO:0000269 PubMed:11308397, ECO:0000269 PubMed:25381065}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry. Susceptibility to intervertebral disk disease is conferred by variant p.Arg103Trp (PubMed:11308397). {ECO:0000269 PubMed:11308397}.
  • Multiple epiphyseal dysplasia 3 (EDM3) [MIM:600969]: A generalized skeletal dysplasia associated with significant morbidity. Joint pain, joint deformity, waddling gait, and short stature are the main clinical signs and symptoms. Radiological examination of the skeleton shows delayed, irregular mineralization of the epiphyseal ossification centers and of the centers of the carpal and tarsal bones. Multiple epiphyseal dysplasia is broadly categorized into the more severe Fairbank and the milder Ribbing types. The Fairbank type is characterized by shortness of stature, short and stubby fingers, small epiphyses in several joints, including the knee, ankle, hand, and hip. The Ribbing type is confined predominantly to the hip joints and is characterized by hands that are normal and stature that is normal or near-normal. {ECO:0000269 PubMed:10090888, ECO:0000269 PubMed:25381065}. Note=The disease is caused by mutations affecting the gene represented in this entry.
