Therefore, it has been classified as a Variant of Uncertain Significance. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 638065). This missense change has been observed in individual(s) with SPONASTRIME Dysplasia (PMID: 30773277). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 494 of the TONSL protein (p.Glu494Lys). This variant also falls at the last nucleotide of exon 11, which is part of the consensus splice site for this exon. |
