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

SCL2A10 NM_030777.3 exon 2 p.Val108Ile (c.322G>A): This variant has not been reported in the literature but is present in 0.007% (5/68034) of European alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/20-46725358-G-A?dataset=gnomad_r3). This variant is present in ClinVar (Variation ID:409250). This variant amino acid Isoleucine (Ile) is present in several 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 is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -

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

This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 108 of the SLC2A10 protein (p.Val108Ile). This variant is present in population databases (rs373375540, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with SLC2A10-related conditions. ClinVar contains an entry for this variant (Variation ID: 409250). 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 not 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. -

Ambry Genetics
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. -
