Sarah Leigh (Genomics England Curator)

Green List (high evidence)

The rating of this gene has been updated to Green and the mode of inheritance set to BIALLELIC, autosomal or pseudoautosomal following NHS Genomic Medicine Service approval.

Arina Puzriakova (Genomics England Curator)

Comment on list classification: There is now sufficient evidence to rate this gene as Green at the next GMS panel update.

Third family reported by Billon et al. 2020 (PMID: 32621347) with the same homozygous exon 4 deletion of MYL9 as the one detected by Moreno et al. 2018 (PMID: 29453416) in an unrelated case. Family includes three sibs affected with megacystis, intestinal malrotation, small and thin colon, as well as some dysmorphic features. Fetopathological examination confirmed the diagnosis of MMIHS.

Panel Version: 3.73
Comment on list classification: Upgraded from Red to Amber as there are now two unrelated families presenting features of MMIHS, associated with different biallelic variants in the MYL9 gene (PMIDs: 29453416; 33031641).

Additional cases/functional evidence required prior to inclusion as diagnostic-grade.
