Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the COL1A1 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000000088.4. 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: Type I collagen is a member of group I collagen (fibrillar forming collagen).
• Disease: DISEASE: Caffey disease (CAFFD) [MIM:114000]: Characterized by an infantile episode of massive subperiosteal new bone formation that typically involves the diaphyses of the long bones, mandible, and clavicles. The involved bones may also appear inflamed, with painful swelling and systemic fever often accompanying the illness. The bone changes usually begin before 5 months of age and resolve before 2 years of age. {ECO:0000269|PubMed:15864348}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Ehlers-Danlos syndrome, classic type, 1 (EDSCL1) [MIM:130000]: A form of Ehlers-Danlos syndrome, a group of connective tissue disorders characterized by skin hyperextensibility, articular hypermobility, and tissue fragility. The main features of classic Ehlers-Danlos syndrome are joint hypermobility and dislocation, and fragile, bruisable skin. EDSCL1 inheritance is autosomal dominant. {ECO:0000269|PubMed:10739762, ECO:0000269|PubMed:17211858}. Note=The disease may be caused by mutations affecting the gene represented in this entry.; DISEASE: Ehlers-Danlos syndrome, arthrochalasia type, 1 (EDSARTH1) [MIM:130060]: A form of Ehlers-Danlos syndrome, a connective tissue disorder characterized by hyperextensible skin, atrophic cutaneous scars due to tissue fragility and joint hyperlaxity. EDSARTH1 is an autosomal dominant form characterized by frequent congenital hip dislocation and extreme joint laxity with recurrent joint subluxations and minimal skin involvement. {ECO:0000269|PubMed:18409203, ECO:0000269|PubMed:9295084}.

Extraskeletal manifestations, which affect a variable number of patients, are dentinogenesis imperfecta, hearing loss, and blue sclerae.
