Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the TGFB2 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: Transforming growth factor beta-2 proprotein: Precursor of the Latency-associated peptide (LAP) and Transforming growth factor beta-2 (TGF-beta-2) chains, which constitute the regulatory and active subunit of TGF-beta-2, respectively. {ECO:0000250|UniProtKB:P01137, ECO:0000250|UniProtKB:P04202}.; FUNCTION: Transforming growth factor beta-2: Multifunctional protein that regulates various processes such as angiogenesis and heart development (PubMed:22772371, PubMed:22772368). Activation into mature form follows different steps: following cleavage of the proprotein in the Golgi apparatus, Latency-associated peptide (LAP) and Transforming growth factor beta-2 (TGF-beta-2) chains remain non-covalently linked rendering TGF-beta-2 inactive during storage in extracellular matrix (By similarity). At the same time, LAP chain interacts with 'milieu molecules', such as LTBP1 and LRRC32/GARP, that control activation of TGF-beta-2 and maintain it in a latent state during storage in extracellular milieus (By similarity). Once activated following release of LAP, TGF-beta-2 acts by binding to TGF-beta receptors (TGFBR1 and TGFBR2), which transduce signal (By similarity). {ECO:0000250|UniProtKB:P01137, ECO:0000250|UniProtKB:P04202, ECO:0000269|PubMed:22772368, ECO:0000269|PubMed:22772371}.
• Disease: DISEASE: Note=A chromosomal aberration involving TGFB2 is found in a family with Peters anomaly. Translocation t(1;7)(q41;p21) with HDAC9. {ECO:0000269|PubMed:12706107}.; DISEASE: Loeys-Dietz syndrome 4 (LDS4) [MIM:614816]: An aortic aneurysm syndrome with widespread systemic involvement. LDS4 is characterized by arterial tortuosity, aortic dissection, intracranial aneurysm and subarachnoid hemorrhage, hypertelorism, bifid uvula, pectus deformity, bicuspid aortic valve, arachnodactyly, scoliosis, foot deformities, dural ectasia, joint hyperflexibility, and thin skin with easy bruising and striae. {ECO:0000269|PubMed:22772368, ECO:0000269|PubMed:22772371}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Note=Defects in TGFB2 may be a cause of non-syndromic aortic disease (NSAD). NSAD is a frequently asymptomatic but potentially lethal disease characterized by thoracic aortic aneurysms and dissections without additional syndromic features. {ECO:0000269|PubMed:25046559}.
