Ambry Genetics | RCV002390452 | SCV002675232 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2021-10-07 | criteria provided, single submitter | clinical testing | The p.N2533S variant (also known as c.7598A>G), located in coding exon 61 of the FBN1 gene, results from an A to G substitution at nucleotide position 7598. The asparagine at codon 2533 is replaced by serine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV003114329 | SCV003800650 | uncertain significance | not specified | 2023-01-09 | criteria provided, single submitter | clinical testing | Variant summary: FBN1 c.7598A>G (p.Asn2533Ser) results in a conservative amino acid change located in the EGF-like domain (IPR000742) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 250664 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.7598A>G in individuals affected with Marfan Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. |
