Sunayna Best (Leeds Teaching Hospitals NHS Trust)

Green List (high evidence)

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).

Dharmadhikari et al, 2025: reported on 28 individuals with biallelic SPOUT1 variants. No specific mention of prenatal phenotype but 18/28 (64%) had abnormal brain MRI findings which I think would be detectable antenatally in many (notable findings including cerebral atrophy with enlarged ventricles, T2 hyperintensity in the white matter, and thinning of the corpus callosum). Extensive functional work.
