Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the TUBA3D gene is commonly pathogenic or not. These statistics are base on transcript: NM_000080386.4. 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: Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain.
• Disease: DISEASE: Keratoconus 9 (KTCN9) [MIM:617928]: An autosomal dominant form of keratoconus, a common degenerative corneal disease characterized by progressive, non-inflammatory thinning of the corneal stroma, corneal ectasia, and cone-shaped corneal protrusion that results in reduced vision. {ECO:0000269|PubMed:29051577}. Note=The disease is caused by mutations affecting the gene represented in this entry.
