Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the MATN3 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000002381.5. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Major component of the extracellular matrix of cartilage and may play a role in the formation of extracellular filamentous networks.
• Disease: DISEASE: Spondyloepimetaphyseal dysplasia MATN3-related (SEMD- MATN3) [MIM:608728]: A bone disease characterized by disproportionate early-onset dwarfism, bowing of the lower limbs, lumbar lordosis and normal hands. Skeletal abnormalities include short, wide and stocky long bones with severe epiphyseal and metaphyseal changes, hypoplastic iliac bones and flat, ovoid vertebral bodies. {ECO:0000269|PubMed:15121775}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Osteoarthritis 2 (OS2) [MIM:140600]: A degenerative disease of the joints characterized by degradation of the hyaline articular cartilage and remodeling of the subchondral bone with sclerosis. Clinical symptoms include pain and joint stiffness often leading to significant disability and joint replacement. In the hand, osteoarthritis can develop in the distal interphalangeal and the first carpometacarpal (base of thumb) and proximal interphalangeal joints. Patients with osteoarthritis may have one, a few, or all of these sites affected. {ECO:0000269|PubMed:12736871}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
