Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The SLC2A10 c.1351T>G; p.Cys451Gly variant (rs199599532), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 213736). This variant is found in the general population with an overall allele frequency of 0.004% (11/251,490 alleles) in the Genome Aggregation Database. Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.553). Due to limited information, the clinical significance of this variant is uncertain at this time.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces cysteine with glycine at codon 451 of the SLC2A10 protein (p.Cys451Gly). The cysteine residue is highly conserved and there is a large physicochemical difference between cysteine and glycine. This variant is present in population databases (rs199599532, ExAC 0.03%). This variant has not been reported in the literature in individuals affected with SLC2A10-related conditions. 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 (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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.

Familial thoracic aortic aneurysm and aortic dissection Uncertain:1

Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1351T>G (p.C451G) alteration is located in exon 3 (coding exon 3) of the SLC2A10 gene. This alteration results from a T to G substitution at nucleotide position 1351, causing the cysteine (C) at amino acid position 451 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
