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.

Collection Method:clinical testing

The p.Ala106Gly variant (rs144095826) has not been reported in the medical literature or gene specific variation databases but it has been reported to ClinVar (Variation ID: 213713). This variant is listed in the NHLBI GO Exome Sequencing Project with an overall population frequency of 0.02 percent (identified on 2 out of 13,006 chromosomes) and is listed in the Exome Aggregation Consortium Browser with an overall population frequency of 0.009 percent (identified on 11 out of 121,100 chromosomes). The alanine at position 106 is weakly conserved (Alamut v.2.8.1) and computational analyses of the effects of the p.Ala106Gly variant on protein structure and function provide conflicting results (SIFT: damaging, MutationTaster: polymorphism, PolyPhen-2: benign). Altogether, there is not enough evidence to classify the p.Ala106Gly variant with certainty.

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely 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.

Collection Method:clinical testing

Variant summary: SLC2A10 c.317C>G (p.Ala106Gly) results in a non-conservative amino acid change located in the Major facilitator superfamily domain (IPR020846) of 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 0.00012 in 250946 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in SLC2A10 causing Aortopathy (0.00012 vs 0.0016), allowing no conclusion about variant significance. c.317C>G has been reported in the literature in one individual who had suspicion of heritable connective tissue disorders (Veatch_2022). This report does not provide unequivocal conclusions about association of the variant with Aortopathy. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. ClinVar contains an entry for this variant (Variation ID: 213713). Based on the evidence outlined above, the variant was classified as uncertain significance.
