Variant summary
Our verdict is Pathogenic. Variant got 13 ACMG points: 13P and 0B. PM1PM2PM5PP2PP3_StrongPP5_Moderate
The NM_000138.5(FBN1):c.5720A>G(p.Asn1907Ser) 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. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N1907D) has been classified as Likely pathogenic.

Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Aug 30, 2019 | Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has been reported in several individuals affected with Marfan syndrome (PMID: 27906200, 17657824). ClinVar contains an entry for this variant (Variation ID: 406360). This variant is not present in population databases (ExAC no frequency). This sequence change replaces asparagine with serine at codon 1907 of the FBN1 protein (p.Asn1907Ser). The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and serine. A different missense substitution at this codon (p.Asn1907Lys) has been reported in an individual affected with Marfan syndrome (PMID: 24793577). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. - |
