Panel Version: 4.192
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.

Natalie Canham (Liverpool Women's Hospital)

Green List (high evidence)

Three papers, each with a single family (with at least two affected sibs). Variants all homozygous missense, will be difficult to interpret any other variants. Convincing phenotype though. Also identified two further papers 36303863 35045414 with a single case each. Green
