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.

Green List (high evidence)

Green in two panels including severe paediatric disorders. Hamamy syndrome charaterised by severe hypertelorism with midface prominence, myopia, mental retardation, and bone fragility. Review of all cases in PMID:34899143 in total 9 patients across 4 families although 1 family with sparse info so 7 patients in 3 families. All had severe telecanthus, braod nasal bridge and long bone fractures (some reported as early as 1 week old). 4/7 cardivascular defects, 3/7 caraniosynotsosis, 5/7 brachcephaly, 3/7 micrognathia. Green.
