| Monogenic hearing loss v2.60 | TMTC2 | Eleanor Williams Classified gene: TMTC2 as Amber List (moderate evidence) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Monogenic hearing loss v2.60 | TMTC2 | Eleanor Williams Added comment: Comment on list classification: Changing rating from grey to amber. Two families reported. Same variant in each. Both northern european decent. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Monogenic hearing loss v2.60 | TMTC2 | Eleanor Williams Gene: tmtc2 has been classified as Amber List (Moderate Evidence). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Monogenic hearing loss v2.59 | TMTC2 | Eleanor Williams Phenotypes for gene: TMTC2 were changed from Deafness to Deafness; Sensorineural hearing loss | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Monogenic hearing loss v2.58 | TMTC2 | Eleanor Williams Added comment: Comment on mode of inheritance: Changing to imprinted status unknown. In one family the trait had been passed through the maternal side for two generations, but more evidence needed before saying paternally imprinted. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Monogenic hearing loss v2.58 | TMTC2 | Eleanor Williams Mode of inheritance for gene: TMTC2 was changed from MONOALLELIC, autosomal or pseudoautosomal, paternally imprinted (maternal allele expressed) to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Monogenic hearing loss v2.57 | TMTC2 |
Eleanor Williams changed review comment from: Not associated with a phenotype in OMIM. PMID: 29671961- Guillen‐Ahlers et al 2018 - report a mother and son with of Northern European descent (mother and son) with Sensorineural hearing loss were found by exome sequencing to share a variant (rs35725509, missense variant) in the TMTC2 gene. This variant showed a minor allele frequency below 1% in 2,203 individuals of European American (EA) ancestry (NHLBI GO Exome Sequencing Project. PMID: 27311106 - Runge et al 2016 - report a large multigenerational Northern European family in which 9 family members had bilateral, symmetric, progressive Sensorineural hearing loss that reached severe to profound loss in childhood. Using exome sequencing and linkage and association analyses they identified a fully penetrant sequence variant (rs35725509) in the TMTC2 gene region. The variant segregates with SNHL in the family. However, the mutation is found in a relatively high percentage of individuals of Northern European descent in the 1000 Genomes and Exome Sequencing (http://evs.gs.washington.edu/EVS/) European call sets (1% and 0.8%, respectively).; to: Not associated with a phenotype in OMIM.
