Natalie Chandler (North Thames GLH)

I don't know

This gene and phenotype were reviewed during meetings in June & July 2025. 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 & Elizabeth Scotchman (North Thames GLH), Natalie Bibb, Stephanie Allen & Sarah Graham (Central & South GLH) and Alice Gardham, Esther Kinning, Vicki Harrison, Anna DeBurca, Natalie Canham, Elizabeth Wall, Sunayna Best, Soo-Mi Park & Sahar Mansour (R21 Clinical Oversight Group).

Comments from prev reivew: Four cases across three families in a single paper. There do appear to be prenatal (brain) presentations. Much better evidence for GTPBP2 which is already on fetal anomalies panel. There are no newer papers (pubmed, omim, hgmd) so recommend to keep amber.
