Monogenic hearing loss v2.225 COL11A1 Eleanor Williams Tag for-review was removed from gene: COL11A1.
Monogenic hearing loss v2.221 COL11A1 Eleanor Williams commented on gene: COL11A1: The rating of this gene has been updated following NHS Genomic Medicine Service approval.
Monogenic hearing loss v2.220 COL11A1 Eleanor Williams Source Expert Review Green was added to COL11A1.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Monogenic hearing loss v2.201 COL11A1 Arina Puzriakova Phenotypes for gene: COL11A1 were changed from Stickler syndrome, type II, MIM#604841; Deafness, autosomal dominant 37, MIM#618533 to Deafness, autosomal dominant 37, OMIM:618533; Stickler syndrome, type II, OMIM:604841
Monogenic hearing loss v2.94 COL2A1 Eleanor Williams changed review comment from: Associated with Stickler syndrome, type I #108300 (AD) in OMIM.

PMID: 23110709 - Acke et al 2012 - review the literature to give an overview of hearing loss in Stickler syndrome, correlated with the genotype. 313 patients from 102 families were reviewed. Hearing loss was found in 62.9%, mostly mild to moderate when reported. Mutations in COL11A1 (82.5%) and COL11A2 (94.1%) seem to be more frequently associated with hearing impairment than mutations in COL2A1 (52.2%).

PMID: 27408751 - Kondo et al 2016 - report 21 cases (some familial, most sporadic) with COL2A1 variants. 4/21 showed hearing loss.

PMID: 20179744 - Hoornaert et al 2010 - identified 77 different heterozygous COL2A1 mutations in 100 affected individuals out of a group of 188 individuals referred with a potential diagnosis of Stickler syndrome. 30% of COL2A1-variant positive patients had sensorineural hearing loss. However, over a higher percentage (50%) of patients without a COL2A1 mutation have sensorineural hearing loss.; to: Associated with Stickler syndrome, type I #108300 (AD) in OMIM.

Monogenic hearing loss v2.94 COL11A1 Eleanor Williams Classified gene: COL11A1 as Amber List (moderate evidence)
Monogenic hearing loss v2.94 COL11A1 Eleanor Williams Added comment: Comment on list classification: After consultation with the Genomics England clinical team it has been decided that this gene has sufficient cases with hearing loss to be promoted to green. Therefore this gene should be reviewed at the next GMS update.
Monogenic hearing loss v2.94 COL11A1 Eleanor Williams Gene: col11a1 has been classified as Amber List (Moderate Evidence).
Monogenic hearing loss v2.93 COL11A1 Eleanor Williams edited their review of gene: COL11A1: Changed rating: GREEN
Monogenic hearing loss v2.89 COL11A1 Eleanor Williams Tag for-review tag was added to gene: COL11A1.
Monogenic hearing loss v2.77 COL11A1 Eleanor Williams commented on gene: COL11A1: PMID: 23967202 - Miyagawa et al 2013 - report 3 missense variants in Japanese hearing loss patients through targeted exome sequencing. 1 familial case shown with two affected siblings. They suggest the inheritance is autosomal dominant.
