Fetal anomalies v6.12 MYH3 Arina Puzriakova Phenotypes for gene: MYH3 were changed from DISTAL ARTHROGRYPOSIS TYPE 2B; DISTAL ARTHROGRYPOSIS TYPE 2A to Arthrogryposis, distal, type 2A (Freeman-Sheldon), OMIM:193700 (AD); Arthrogryposis, distal, type 2B3 (Sheldon-Hall), OMIM:618436 (AD); Contractures, pterygia, and spondylocarpostarsal fusion syndrome 1A, OMIM:178110 (AD); Contractures, pterygia, and spondylocarpotarsal fusion syndrome 1B, OMIM:618469 (AR)
Fetal anomalies v6.10 MYH3 Arina Puzriakova Added comment: Comment on mode of inheritance: MOI should be changed from 'MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown' to 'BOTH monoallelic and biallelic, autosomal or pseudoautosomal' at the next GMS panel update.

Monoallelic variants are associated with distal arthrogryposis conditions including Freeman-Sheldon syndrome and Sheldon-Hall syndrome.

Monoallelic and biallelic variants also underlie Contractures, Pterygia, and Spondylocarpotarsal Fusion syndromes (CPSFS) which are characterised by extensive bony abnormalities in addition to congenital contractures. These features could be detected prenatally and therefore are relevant to this panel.

At least 3 unrelated recessive CPSFS cases have been reported with multiple contractures (PMID: 29805041). Additionally, two sibs from one family have been reported with distal arthrogryposis without additional features of CPSFS, who harboured two homozygous ultra-rare MYH3 variants (PMID: 38856159). Their presentation was assessed in a prenatal diagnostic setting. Overall this evidence supports an MOI of 'both mono- and biallelic' on this panel.
Fetal anomalies v0.166 ARSA Rebecca Foulger edited their review of gene: ARSA: Added comment: This gene and phenotype were discussed during review of borderline cases in April 2019. Clinical review and curation was performed by Lyn Chitty, Anna de Burca, Rhiannon Mellis, Richard Scott, Ellen McDonagh and Rebecca Foulger. Outcome of review: Confirmed that phenotype is fetally-relevant: keep on the Fetal anomalies panel as Green. Additional notes from clinical review: Can cause leukodystrophy.; Changed rating: GREEN
