Reported in a female child with arterial tortuosity syndrome, atrial septal defect, inguinal hernia, and corneal thinning who also harbored an additional variant in the SLC2A10 gene (Hardin et al., 2018); Not observed at a significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 23142374, 28726533) -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.A283D variant (also known as c.848C>A), located in coding exon 2 of the SLC2A10 gene, results from a C to A substitution at nucleotide position 848. The alanine at codon 283 is replaced by aspartic acid, an amino acid with dissimilar properties. This alteration was reported as a compound heterozygote in a seven year old female with arterial tortuosity, atrial septal defect and corneal thinning (Hardin JS et al. Ophthalmic Genet, 2018 Jul;39:29-34). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces alanine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 283 of the SLC2A10 protein (p.Ala283Asp). This variant is present in population databases (rs145994112, gnomAD 0.008%). This missense change has been observed in individual(s) with arterial tortuosity syndrome (PMID: 28726533). ClinVar contains an entry for this variant (Variation ID: 213748). 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. 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. -
