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 cilliopathies (various) & retinal disorder panels. PMID: 33791682 11 individuals in 6 families with homozygous or compound heterozygous missense and nonsense (1) variants, with a Joubert/Meckel syndrome phenotype. Clinical features included the molar tooth sign (N=2), occipital encephalocele (N=5, all fetuses), retinal dystrophy (N=4, all living individuals), polycystic kidneys (N=2), and polydactyly (N=2), without liver involvement. A null mouse model had nephronophthisis and retinal degeneration. PMID:35137054 3 more cases -2 families plu zebrafish. Green
