Arina Puzriakova (Genomics England Curator)

Green List (high evidence)

Upgraded from Red to Amber but there is sufficient evidence to make Green at the next GMS panel update, inline with the recent review by the R21 Clinical Oversight Group.

Sarah Graham (West Midlands Regional Genetics Laboratory, Birmingham Women's and Children’s NHS Foundation 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).

Galactosemia typically presents neonatally after ingestion of galactose. Other galactosemia genes GALK1 and GALE are on panel due to association with cataracts. No evidence for prenatal development of cataracts or other prenatal manifestations with any galactosemia genes, but actionable finding postnatally. Should be on panel if GALK1 and GALE are.

Rebecca Foulger (Genomics England curator)

Red List (low evidence)

This gene and phenotype were reviewed during meetings at Great Ormond Street hospital in March 2019. Clinical review and curation was performed by Lyn Chitty, Anna de Burca, Rhiannon Mellis, Richard Scott, Ellen McDonagh and Rebecca Foulger. Outcome of review: Phenotype is not fetally-relevant. Additional notes from clinical review: Nothing detectable prenatally, though it would be informative as clinically actionable at birth. Action taken: Demoted GALT gene rating from Green to Red.
