Intellectual disability v9.72 EXOSC8 Arina Puzriakova edited their review of gene: EXOSC8: Added comment: PMID: 34210538 (2021) - 16-year-old Spanish boy with cerebellar and spinal muscular atrophy, spasticity, psychomotor retardation, nystagmus, ophthalmoparesis, epilepsy, and mitochondrial respiratory chain (MRC) deficiency. The phenotype was described as milder compared to previous cases. WES revealed three variants in the EXOSC8 gene (c.[390+1delG];[628C>T;815G>C]) which lead to reduced mRNA expression and protein levels.

PMID: 38017281 (2024) - Homozygous missense variant c.238G>A;p.Val80Ile causing exon skipping in a patient with psychomotor retardation, spasticity, spinal muscle atrophy, respiratory problems, diaphragmatic hernia, dilated lateral ventricles, hypoplastic temporal lobes, thinning of the brain stem, dysmorphic facies, nystagmus, congenital esotropia and contractures.; Changed rating: GREEN; Changed publications to: 24989451, 38017281, 34210538
