Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the TGFBI gene is commonly pathogenic or not.

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: Plays a role in cell adhesion (PubMed:8024701). May play a role in cell-collagen interactions (By similarity). {ECO:0000250|UniProtKB:O11780, ECO:0000269|PubMed:8024701}.
• Disease: DISEASE: Corneal dystrophy, epithelial basement membrane (EBMD) [MIM:121820]: A bilateral anterior corneal dystrophy characterized by grayish epithelial fingerprint lines, geographic map-like lines, and dots (or microcysts) on slit-lamp examination. Pathologic studies show abnormal, redundant basement membrane and intraepithelial lacunae filled with cellular debris. {ECO:0000269|PubMed:16652336}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Corneal dystrophy, Groenouw type 1 (CDGG1) [MIM:121900]: A rare form of stromal corneal dystrophy characterized by multiple small deposits in the superficial central corneal stroma, and progressive visual impairment. {ECO:0000269|PubMed:15623763}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Corneal dystrophy, lattice type 1 (CDL1) [MIM:122200]: A form of lattice corneal dystrophy, a class of inherited stromal amyloidoses characterized by pathognomonic branching lattice figures in the cornea. CDL1 is characterized by progressive visual impairment, and the presence of delicate, double-contoured, interdigitating, elongated deposits that form a reticular pattern in the corneal stroma. Systemic amyloidosis is absent. Recurrent corneal ulceration sometimes occurs. {ECO:0000269|PubMed:10837380, ECO:0000269|PubMed:11413411, ECO:0000269|PubMed:14597039, ECO:0000269|PubMed:15531312, ECO:0000269|PubMed:15623763, ECO:0000269|PubMed:15838722, ECO:0000269|PubMed:16541014, ECO:0000269|PubMed:17013691, ECO:0000269|PubMed:9799082}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Corneal dystrophy, Thiel-Behnke type (CDTB) [MIM:602082]: A bilateral disorder of the cornea characterized by progressive honeycomb-like, subepithelial corneal opacities with recurrent erosions. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Corneal dystrophy, Reis-Bucklers type (CDRB) [MIM:608470]: A bilateral disorder of the cornea characterized by intermittent attacks of ocular irritation, recurrent painful corneal erosions starting in childhood, corneal opacities in a geographic pattern at the level of the Bowman layer, and a progressive decrease of visual acuity. The lesions are primarily in Bowman membrane with secondary involvement of the epithelium and superficial part of the stroma. Bowman membrane is almost completely replaced by pathologic materials including disoriented collagen fibrils. {ECO:0000269|PubMed:10660331, ECO:0000269|PubMed:15623763, ECO:0000269|PubMed:9780098}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Corneal dystrophy, lattice type 3A (CDL3A) [MIM:608471]: A form of lattice corneal dystrophy, a class of inherited stromal amyloidoses characterized by pathognomonic branching lattice figures in the cornea. CDL3A is characterized by decreased visual acuity, and the presence of thick, ropy branching lattice lines and accumulations of amyloid deposits in the corneal stroma. Systemic amyloidosis is absent. CDL3A clinically resembles to lattice corneal dystrophy type 3, but differs in that its age of onset is 70 to 90 years. It has an autosomal dominant inheritance pattern. {ECO:0000269|PubMed:15790870, ECO:0000269|PubMed:9497262}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Corneal dystrophy, Avellino type (CDA) [MIM:607541]: A corneal disease resulting in reduced visual acuity and characterized by gray, crumb-like granular deposits in the anterior third of the stroma in each corneal button. Fusiform amyloid deposits, histochemically and morphologically identical to those of lattice corneal dystrophy, are found in the deeper stroma. Additional features include recurrent corneal erosions, and glare and decreased night vision. Note=The disease is caused by mutations affecting the gene represented in this entry.
