Krithika Murali gene: UNC79 was added gene: UNC79 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: UNC79 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: UNC79 were set to PMID:37183800 Phenotypes for gene: UNC79 were set to Neurodevelopmental disorderMONDO:0700092 Review for gene: UNC79 was set to AMBER Added comment: PMID:37183800 Bayat et al 2023 report 6 unrelated patients with heterozygous NMD-predicted LoF variants in UNC79 - x1 canonical splice site variant, x5 nonsense/frameshift. 5 were confirmed de novo, 1 not identified in mother - father unavailable for testing. All variants absent in gnomAD and v2 pLI score for UNC79 is 1. Patients with UNC79 variants were identified through GeneMatcher or an international network of Epilepsy and Genetics departments. x1 patient underwent duo exome sequencing, remaining had trio exome sequencing - no other causative variants identified. Phenotypic features included: - 4/6 autistic features - 5/6 patients mild-moderate ID - 4/6 behavioural issues (aggression, stereotypies) - 4/6 epilepsy (focal to bilateral tonic-clonic seizures) - 5/6 hypotonia unc79 knockdown drosophila flies exhibited significantly higher rate of seizure-like behaviour than controls. unc79 haploinsufficiency shown to lead to significant reduction in protein levels of both unc79 and unc80 in mouse brains. Unc79 haploinsufficiency associated with deficiency in hippocampal-dependent learning and memory in mice. Authors have reviewed their own evidence in relation to the gene-disease criteria detailed by Strande et al 2017 and note that their clinical and experimental data provides moderate-level evidence supporting the association between UNC79 and a neurodevelopment disorder including ASD. Amber association favoured due to clinical phenotypic range reported between affected individuals and their lack of specificity. Sources: Literature |
