Elizabeth Scotchman (North Thames Genomic Laboratory Hub)

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).

Green on Australian fetal anomalies panel. PMID 38821050: identification of biallelic missense variants in DHRSX in four patients from three unrelated families with a congenital disorder of glycosylation. They displayed distinct facial features, severe neurological involvement including hypotonia, scoliosis, contractures, profound intellectual disability, epilepsy, and sensorineural hearing loss. These patients also experienced severe failure to thrive (requiring tube feeding); variable respiratory insufficiency; and involvement of the eyes, the gastrointestinal system, and other organs. Contractures and brain anomalies may be detectable antenatally.
