Variant summary
Our verdict is Benign. Variant got -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2
The NM_030777.4(SLC2A10):c.674G>A(p.Arg225His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000915 in 1,614,086 control chromosomes in the GnomAD database, including 9 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R225C) has been classified as Uncertain significance.

Submissions by phenotype
not specified Benign:4
Benign, criteria provided, single submitter | clinical testing | GeneDx | Jul 29, 2015 | 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. - |

Likely benign, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Jan 15, 2024 | Variant summary: SLC2A10 c.674G>A (p.Arg225His) results in a non-conservative amino acid change located in the Major facilitator superfamily domain (IPR020846) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0015 in 250864 control chromosomes, including 3 homozygotes, predominantly at a frequency of 0.0089 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 5.6 fold of 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 a benign polymorphism found primarily in populations of African or African-American origin. c.674G>A has been reported in the literature in at least one homozygous individual affected with Arterial Tortuosity Syndrome (e.g., Beyens_2018). 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: 29323665). ClinVar contains an entry for this variant (Variation ID: 241606). Based on the evidence outlined above, the variant was classified as likely benign. - |

Familial thoracic aortic aneurysm and aortic dissection Benign:2
Benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 20, 2015 | 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. - |
