Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant has been reported in the literature in one individual with aortic dilation/dissection (Wooderchak-Donahue 2015 PMID:25944730). However, this variant is also present in 0.1% (174/129040) of European alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/20-45354190-C-T) and is present in ClinVar, with several labs classifying this variant as benign or likely benign (Variation ID:195383). This variant amino acid Isoleucine (Ile) is present in >15 species and is not well conserved among evolutionarily distant species; this suggests that this variant may not impact the protein. Additional computational prediction tools do not suggest an impact. In summary, data on this variant suggests that this variant does not cause disease, but requires further evidence. Therefore this variant is classified as likely benign. -

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

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

The SLC2A10 c.515C>T; p.Thr172Ile variant (rs143301610) is reported in the literature in an individual affected with aortopathy/aortic dilation (Wooderchak-Donahue 2015), but its clinical significance was not determined. This variant is also reported in ClinVar (Variation ID: 195383) and is found in the non-Finnish European population with an allele frequency of 0.135% (174/129040 alleles) in the Genome Aggregation Database. The threonine at codon 172 is weakly conserved, and computational analyses predict that this variant is neutral (REVEL: 0.148). Due to limited information, the clinical significance of the p.Thr172Ile variant is uncertain at this time.

Variant summary: SLC2A10 c.515C>T (p.Thr172Ile) results in a non-conservative amino acid change located in the Major facilitator superfamily domain (IPR020846) of the encoded protein sequence. Three of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0014 in 1614086 control chromosomes, predominantly at a frequency of 0.0017 within the Non-Finnish European subpopulation in the gnomAD database (v4.0.0). The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is higher than the estimated maximal expected allele frequency for a pathogenic variant in SLC2A10 causing Arterial Tortuosity Syndrome phenotype (0.0016). The variant, c.515C>T, has been reported in the literature in an individual with aortic dilation or dissection, however, further details were not provided on this case (Wooderchak-Donahue_2015). These report(s) do not provide unequivocal conclusions about association of the variant with Arterial Tortuosity Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 25944730). ClinVar contains an entry for this variant (Variation ID: 195383). Based on the evidence outlined above, the variant was classified as likely benign. -

Variant classified as Uncertain Significance - Favor Benign. The p.Thr172Ile in SLC2A10 has not been previously reported in individuals with connective tissue d isorders, but has been identified in 0.1% (8/6610) of Finnish chromosomes and 0. 1% (81/66602) of European chromosomes by the Exome Aggregation Consortium (http: //exac.broadinstitute.org; dbSNP rs143301610). Threonine (Thr) at position 172 i s not conserved in mammals or evolutionarily distant species and several birds, reptiles, and fish carry an isoleucine (Ile) at this position, supporting that t his change may be tolerated. In summary, while the clinical significance of the p.Thr172Ile variant is uncertain, these data suggest that it is more likely to b e benign. -

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
