| Genetic Epilepsy v1.171 | SNW1 |
Lucy Spencer gene: SNW1 was added gene: SNW1 was added to Genetic Epilepsy. Sources: Literature Mode of inheritance for gene: SNW1 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: SNW1 were set to 40608414 Phenotypes for gene: SNW1 were set to Neurodevelopmental disorder (MONDO:0700092), SNW1-related Review for gene: SNW1 was set to GREEN Added comment: cohort of 9 patients with moderate to profound ID, microcephaly, seizures (7/9), facial dysmorphism, and brain malformations (6/9 - corpus callosum hypoplasia, Dandy-Walker malformation). 3 splice, 1 frameshift, 2 missense, 3 in frame deletions, 1 start loss. all but 1 de novo (the last parents not available). SNW1 is a core component of the spliceosome and facilitates the conformational changes of the spliceosome. Expression of variants in HEK293 cells showed some decreased SNW1 expression while others increased it (including the frameshift), and only the frameshift variant was mislocalised/in the cytoplasm instead of the nucleus. Several of the variants caused loss of binding to PPIL1 or other proteins which SNW1 usually recruits to the spliceosome. All variants in this study were found to either affect protein expression or localization or influence interactions with other proteins in the spliceosome complex suggesting loss of function.
