Zornitza Stark gene: IFT57 was added gene: IFT57 was added to Fetal anomalies. Sources: Literature Mode of inheritance for gene: IFT57 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: IFT57 were set to 40273360 Phenotypes for gene: IFT57 were set to Bardet-Bield syndrome; ciliopathy - MONDO:0005308, IFT57-related Review for gene: IFT57 was set to AMBER Added comment: PMID:40273360 Nitoiu et al 2025 report a male with clinical features of Bardet-Biedl syndrome. Phenotypic features include: - Vision issues - night vision loss, progressive cone-rod dystrophy leading to legal blindness - Post-axial polydactyly - Obesity and type 2 diabetes - Learning difficulties - Moderate sensorineural hearing loss Biallelic IFT57 variants were identified on short-read genomic sequencing after negative panel-based clinical testing - NM_018010.4 (IFT57): c.1190 T>A;p.(Val397Glu) and c.675del; p.(Lys225Asnfsā17). Patient-derived fibroblasts had fewer primary cilia, abnormal ciliary morphology and abnormal anterograde transport in the primary cilia. IFT57 knockout mouse models did not form primary cilia. Treatment with IFT57-WT restored cilia formation while IFT57-Val397Glu only partially rescued cilia formation in Ift57-KO-mouse cells. Sources: Literature |
