Respiratory ciliopathies including non-CF bronchiectasis
Gene: TTC12Submitted on behalf of NHS GMS "Only 6 variants in HGMD, all from the one study Thomas et al. Again as in NKE10 its not clear that full variant analysis has been done to ACGS standard, e.g. the homozygous variant c.1700T>G being described as pathogenic appear to be based on PM2 but has low frequency in gnomad and parents are related, PP3, PM1 (tricky to use in a new assocaited gene), and PS3 for study showing reduced TTC12. There is clearly strong evidence in this particular study but would argue that its too soon for inclusion in a diagnostic panel, but warrants further study. Amber genes can be included in panel designs for this research."Created: 8 Mar 2022, 11:15 a.m. | Last Modified: 8 Mar 2022, 11:15 a.m.

Comment on list classification: This gene is associated with a relevant phenotype in OMIM and Gene2Phenotype. There is enough evidence to support a gene-disease association. This gene should be promoted to Green at the next review.Created: 2 Dec 2020, 2:42 p.m. | Last Modified: 2 Dec 2020, 2:42 p.m.
