Invitae | RCV000647666 | SCV000769464 | uncertain significance | Spinocerebellar ataxia, autosomal recessive 8; Emery-Dreifuss muscular dystrophy 4, autosomal dominant | 2017-11-07 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine with histidine at codon 4914 of the SYNE1 protein (p.Gln4914His). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and histidine. This variant also falls at the last nucleotide of exon 77 of the SYNE1 coding sequence, which is part of the consensus splice site for this exon. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with SYNE1-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. Nucleotide substitutions within the consensus splice site are relatively common causes of aberrant splicing (PMID: 17576681, 9536098). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
