Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the TUBGCP6 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: Gamma-tubulin complex is necessary for microtubule nucleation at the centrosome. {ECO:0000269|PubMed:11694571}.
• Disease: DISEASE: Microcephaly and chorioretinopathy, autosomal recessive, 1 (MCCRP1) [MIM:251270]: A syndrome characterized by microcephaly, cognitive impairment, underdeveloped retina and choroid, and epilepsy in some patients. The more anterior parts of the retina, near the periphery and pars plana, have a grayish hue and diminutive vasculature similar to retinopathy of prematurity. Visual impairment becomes evident during the first year of life. {ECO:0000269|PubMed:22279524}. Note=The disease is caused by mutations affecting the gene represented in this entry.
