The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.192%). Predicted Consequence: Non-coding transcript non-coding variant. The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least 2 similarly affected unrelated individuals (PMID: 27571260 / 3billion dataset). Functional studies provide moderate evidence of the variant having a damaging effect on the gene or gene product (PMID: 27571260). The variant has been reported to be associated with SNORD118-related disorder (ClinVar ID: VCV000929273). Therefore, the variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -

Functional studies provide conflicting evidence, with one study suggesting this variant alters processing of the precursor U8 snoRNAs while another study suggests this variant is functional (PMID: 27571260, 32359472); Variant in a snoRNA that alters a C:G Watson-Crick base pair to a U:G wobble base pair in the 3' extension (PMID: 32359472); This variant is associated with the following publications: (PMID: 32359472, 33029936, 27571260, 34426522, 37761957, 36697224, 34937159, 34986804, 34220662, 32400930, 34380746, 31521395, 32358219, 31912665) -
