Likely pathogenic, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Apr 16, 2019	The p.Gly426Trp variant in SLC2A10 has been reported in 3 compound heterozygous and 1 homozygous individuals with arterial tortuosity syndrome (Callewaert 2008, Overwater 2018). It has also been identified in 1/110674 European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This variant has also been reported in ClinVar (Variation ID 4589). Computational prediction tools and conservation analysis suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. This variant is located in the TMD10 functional domain of the SLC2A10 gene (Callewaert 2008). In summary, this variant meets criteria to be classified as likely pathogenic for autosomal recessive arterial tortuosity syndrome. ACMG/AMP Criteria applied: PM2, PP3, PM3_Strong. -

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Oct 03, 2023	This sequence change replaces glycine, which is neutral and non-polar, with tryptophan, which is neutral and slightly polar, at codon 426 of the SLC2A10 protein (p.Gly426Trp). 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 missense change has been observed in individual(s) with arterial tortuosity syndrome and/or thoracic aortic aneurysm (PMID: 17935213, 29907982). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 4589). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt SLC2A10 protein function. For these reasons, this variant has been classified as Pathogenic. -

The p.G426W pathogenic mutation (also known as c.1276G>T), located in coding exon 2 of the SLC2A10 gene, results from a G to T substitution at nucleotide position 1276. The glycine at codon 426 is replaced by tryptophan, an amino acid with highly dissimilar properties. This variant has been detected in three probands with arterial tortuosity syndrome (ATS) who also had a second SLC2A10 variant in trans, one of which was a frameshift alteration (Callewaert BL et al. Hum. Mutat., 2008 Jan;29:150-8). This variant has also been detected in the homozygous state in a pediatric proband with features consistent with ATS (Overwater E et al. Hum. Mutat., 2018 09;39:1173-1192). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -
