Multiple epiphyseal dysplasia and pseudoachondroplasia v0.7 COL9A1 Ain Roesley Marked gene: COL9A1 as ready
Multiple epiphyseal dysplasia and pseudoachondroplasia v0.7 COL9A1 Ain Roesley Gene: col9a1 has been classified as Red List (Low Evidence).
Multiple epiphyseal dysplasia and pseudoachondroplasia v0.7 COL9A1 Ain Roesley Phenotypes for gene: COL9A1 were changed from Stickler syndrome, type IV 614134; Epiphyseal dysplasia, multiple, 6 614135 to Epiphyseal dysplasia, multiple, 6 614135
Multiple epiphyseal dysplasia and pseudoachondroplasia v0.6 COL9A1 Ain Roesley Publications for gene: COL9A1 were set to
Multiple epiphyseal dysplasia and pseudoachondroplasia v0.5 COL9A1 Ain Roesley Classified gene: COL9A1 as Red List (low evidence)
Multiple epiphyseal dysplasia and pseudoachondroplasia v0.5 COL9A1 Ain Roesley Added comment: Comment on list classification: Too many hets in gnomAD for the variants reported thus far
Multiple epiphyseal dysplasia and pseudoachondroplasia v0.5 COL9A1 Ain Roesley Gene: col9a1 has been classified as Red List (Low Evidence).
Multiple epiphyseal dysplasia and pseudoachondroplasia v0.3 COL9A1 Paul De Fazio changed review comment from: Single family with a splice variant, predicted by the authors to result in in-frame exon skipping, reported in 2001 (PMID: 11565064).

A second splice variant was reported in 2017 in an individual with a dual diagnosis of COL9A1 and ATRX (PMID: 27959697). The COL9A1 variant has 19 hets in gnomAD. No phenotypes given in the paper but the individual was reported in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/374336/evidence/).

Heterozygous mice transfected with a COL9A1 intragenic deletion showed changes similiar to osteoarthritis, as do homozygous null mice (PMID: 8197187, 8464901); to: Single family with a splice variant, predicted by the authors to result in in-frame exon skipping, reported in 2001 (PMID: 11565064). Variant has 63 hets in gnomAD.
