Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1423T>G (p.L475V) alteration is located in exon 4 (coding exon 4) of the SLC2A10 gene. This alteration results from a T to G substitution at nucleotide position 1423, causing the leucine (L) at amino acid position 475 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

p.Leu475Val (TTG>GTG): c.1423 T>G in exon 4 of the SLC2A10 gene (NM_030777.3). The Leu475Val variant in the SLC2A10 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Leu475Val results in a conservative amino acid substitution of one non-polar amino acid with another at a position that is conserved in mammals. In silico analysis predicts possibly damaging to the protein structure/function. The NHLBI ESP Exome Variant Server reports Leu475Val was not observed in approximately 6,500 samples from individuals of European and African American backgrounds, indicating it is not a common benign variant in these populations. Nevertheless, no mutations in nearby codons have been reported in association with arterial tortuosity syndrome. With the clinical and molecular information available at this time, we cannot definitively determine if Leu475Val is a disease-causing mutation or a rare benign variant. This variant was found in TAAD -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 475 of the SLC2A10 protein (p.Leu475Val). This variant is present in population databases (rs754355572, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with SLC2A10-related conditions. ClinVar contains an entry for this variant (Variation ID: 213740). 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 not expected to disrupt SLC2A10 protein function. 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. -
