This gene and phenotype were reviewed during meetings between November 2023 & July 2024. The meetings included representatives of the North Thames and Central & South R21 testing GLHs and from the R21 Clinical Oversight Group. Clinical review and curation was performed by Natalie Chandler, Alison Male and Lyn Chitty (North Thames GLH), Stephanie Allen, Natalie Bibb, Esther Kinning and Denise Williams (Central & South GLH) and Natalie Canham, Anna De Burca and Samantha Doyle R21 Clinical Oversight Group. Outcome of review: Confirmed that the phenotype is fetally relevant, support adding to the Fetal anomalies panel as a Green gene.

This review was provided by Alison Male from North Thames GLH: Currently amber. PMID: 34976470 - arthrogryposis multiplex congenita phenotype (AMC) in two male fetuses in a family, caused by splice deletion c.2482-1_2484delGTCA which was mat inherited. No splice studies conducted, mother was normal. Postulate that amorphic or severe null pathogenic variants (possible complete loss of function) lead to AMC phenotype; PMID: 37945483 same variant differnet family but de novo. TOP at 34 weeks hydrops and fetal immobility. HC >97th%, FL<3rd%, clenched hands. Suggest green
