chr5-128287348-C-T
Variant summary
Our verdict is Benign. Variant got -17 ACMG points: 0P and 17B. BP4_StrongBP6_Very_StrongBP7BS2
The NM_001999.4(FBN2):c.6840G>A(p.Pro2280=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000105 in 1,613,836 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. P2280P) has been classified as Likely benign.

not specified Benign:2
Likely benign, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | - | - - |
Likely benign, criteria provided, single submitter | clinical testing | GeneDx | Jan 19, 2018 | 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. - |
Familial thoracic aortic aneurysm and aortic dissection Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 21, 2022 | This alteration is classified as likely 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. - |
