Congenital myopathy
Gene: COL9A3
Comment when marking as ready: MED presentation; appropriate for skeletal panelCreated: 3 Feb 2017, 11:50 a.m.
Comment on list classification: Presents with MED. One family with additional muscle phenotypeCreated: 3 Feb 2017, 11:48 a.m.
Mutations to date in 4 unrelated families with MED have involved in frame deletions (skipping of exon 3). One family reported with a myopathic phenotype in addition, however an unrelated family with the same mutation only had MED. Insufficient evidence for congenital myopathy.Created: 30 Jan 2017, 2:55 p.m.

Phenotypes for gene: COL9A3 were changed from Epiphyseal dysplasia, multiple, 3, with or without myopathy 600969 to Epiphyseal dysplasia, multiple, 3, with or without myopathy, OMIM:600969
Promoted 22/02/2017 after curation discussion and further review with members of the Genomics England curation team. Participants who are offered this panel will automatically be offered the following three panels: 1) Congenital muscular dystrophy 2) Congenital myasthenia and 3) Paediatric motor neuronopathy as this will cover a large range of differentials for a weak infant, for where the strict inclusion criteria are not applicable in view of the availability of muscle biopsy testing in peripheral paediatric units.
This gene has been classified as Red List (Low Evidence).
