Arina Puzriakova (Genomics England Curator)

Comment on mode of inheritance: Should be updated from 'monoallelic' only to 'both mono- and biallelic' at the next GMS review. Two families have been reported (PMID: 32219868) with recessive disease including optic atrophy associated with hearing loss, intellectual disability and ataxia, among others. This was considered sufficient to rate as green under AD/AR inheritance on the Optic neuropathy (R41) panel and therefore this MOI should also be reflected on the Retinal disorders panel.

Green List (high evidence)

Over 20 families reported with optic atrophy and missense variants in this gene, p.R468C is recurrent. Bi-allelic variants reported in two families. Please note gene is also associated with SCA. The ADOA variants mostly are located within or close to the ATPase/AAA domain, while those in the proteolytic domain mostly cause dominant spinocerebellar ataxia type 28 (SCA28) or recessive spastic ataxia with epilepsy (SPAX5) (PMIDs: 32219868, 32600459).

This gene is associated with a relevant phenotype in OMIM, but it is not associated with an eye phenotype in Gene2Phenotype. Based on the available information there is enough evidence to support a gene-disease association. This gene has been tagged with "for-review" and should be promoted to Green at the next review.

Submitted on behalf of the GMS Eye specialist group. These genes are also from RetNet. There is currently not enough evidence to rate these genes Green, therefore they have been given an Amber rating.
