Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: SLC2A10 c.1548-18G>A alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 4/4 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.0019 in 250304 control chromosomes in the gnomAD database, including 5 homozygotes. The observed variant frequency exceeds the estimated maximal expected allele frequency for a pathogenic variant in SLC2A10 causing Arterial Tortuosity Syndrome phenotype (0.0016), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.1548-18G>A in individuals affected with Arterial Tortuosity Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as benign. -
