Green List (high evidence)

Comment on MOI: The MOI of this gene should be changed to 'BIALLELIC, autosomal or pseudoautosomal' as I cannot find any evidence that relates monoallelic variants of this gene with disease phenotype.

This gene has only been associated with phenotypes arising from autosomal recessive/ biallelic inheritance in OMIM (MIM #602771) and Gene2Phenotype and not with any other phenotypes arising from autosomal dominant phenotypes. The OMIM phenotype that was previously associated with SELENON (Myopathy, congenital, with fiber-type disproportion, MIM #255310) has now been associated with TPM3.

In addition, published cases from literature show that biallelic variants (both homozygous and compound heterozygous) in SELENON cause a broad spectrum of myopathy including rigid spine muscular dystrophy, multi-minicore disease, congenital fiber type disproportion and desmin-related myopathy with Mallory body–like inclusions.
