Chirag Patel gene: EXOSC1 was added gene: EXOSC1 was added to Cerebellar and Pontocerebellar Hypoplasia. Sources: Literature Mode of inheritance for gene: EXOSC1 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: EXOSC1 were set to PMID: 33463720 Phenotypes for gene: EXOSC1 were set to Pontocerebellar hypoplasia Review for gene: EXOSC1 was set to RED Added comment: An 8‐months‐old male with developmental delay, microcephaly, subtle dysmorphism, hypotonia, pontocerebellar hypoplasia and delayed myelination. Similarly affected elder sibling succumbed at the age of 4‐years 6‐months. Exome sequencing revealed a homozygous missense variant (c.104C >T, p.Ser35Leu) in EXOSC1. In silico mutagenesis revealed loss of a polar contact with neighbouring Leu37 residue. Quantitative real‐time PCR indicated no appreciable differences in EXOSC1 transcript levels. Immunoblotting and blue native PAGE revealed reduction in the EXOSC1 protein levels and EXO9 complex in the proband, respectively. Of note, bi‐allelic variants in other exosome subunits EXOSC3, EXOSC8 and EXOSC9 have been reported to cause pontocerebellar hypoplasia type 1B, type 1C and type 1D, respectively.
