Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1PM2PP2PP3_Strong
The NM_000138.5(FBN1):c.7640G>T(p.Ser2547Ile) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 10/17 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S2547R) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Sep 22, 2011 | Variant classified as Uncertain Significance - Favor Pathogenic. The Ser2547Ile variant has not been previously reported nor identified by our laboratory. Serin e (Ser) at position 2547 is highly conserved across evolutionarily distant speci es, increasing the likelihood the change may not be tolerated. In addition, the results from multiple computational analyses(AlignGVGD predicts benign, PolyPhen 2 and SIFT predict pathogenic) are mixed, though the accuracy of these tools is unclear. Finally, this variant lies within a functional domain of FBN1, support ing the possibility that Ser2547Ile variant is responsible for the clinical feat ures observed in this individual. Although this data suggests this variant may be pathogenic, we cannot rule out a benign role. In summary, the clinical signif icance of the Ser2547Ile variant cannot be determined at this time and additiona l data is required to fully assess this variant. - |
