RCV000198918 | SCV000250734 | uncertain significance | not provided | 2014-05-16 | criteria provided, single submitter | clinical testing | p.Ser43Arg (AGC>AGG): c.129 C>G in exon 2 of the SLC2A10 gene (NM_030777.3). A variant of unknown significance has been identified in the SLC2A10 gene. The S43R variant has not been published as a mutation nor as a benign polymorphism to our knowledge. The S43R variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The S43R variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved among mammals. Moreover, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function, however at least two models predict this variant is damaging. Nevertheless, no missense mutations in nearby residues have been reported in association with arterial tortuosity syndrome, suggesting this region of the protein may be tolerant of change. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. This variant was found in TAAD,SLC2A10 |
