Familial aortopathy

Women's Health and Genetics/Laboratory Corporation of America, LabCorp

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: SLC2A10 c.395G>A (p.Arg132Gln) results in a conservative amino acid change in the encoded protein sequence. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change. The variant allele was found at a frequency of 6e-05 in 251334 control chromosomes (gnomAD). This frequency is not significantly higher than estimated for a pathogenic variant in SLC2A10 causing Aortopathy (0.0016), allowing no conclusion about variant significance. c.395G>A has been observed in compound heterozygous and homozygous state in individuals affected with Aortopathy (e.g. Beyens_2018). These data indicate that the variant may be associated with disease. In addition, a different variant affecting the same codon has been classified as likely pathogenic/pathogenic by our lab (c.394C>T, p.Arg132Trp), supporting the critical relevance of codon 132 to SLC2A10 protein function. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 30090112, 29323665). ClinVar contains an entry for this variant (Variation ID: 1342029). Based on the evidence outlined above, the variant was classified as likely pathogenic. -

Arterial tortuosity syndrome

Pathogenic:1

May 26, 2024

Labcorp Genetics (formerly Invitae), Labcorp

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 132 of the SLC2A10 protein (p.Arg132Gln). This variant is present in population databases (rs376346077, gnomAD 0.01%). This missense change has been observed in individual(s) with arterial tortuosity syndrome (PMID: 29323665). ClinVar contains an entry for this variant (Variation ID: 1342029). 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 with a positive predictive value of 95%. This variant disrupts the p.Arg132 amino acid residue in SLC2A10. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 17935213, 28726533, 29543232). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
