Genes affected
FBN2 (HGNC:3604): (fibrillin 2) The protein encoded by this gene is a component of connective tissue microfibrils and may be involved in elastic fiber assembly. Mutations in this gene cause congenital contractural arachnodactyly. [provided by RefSeq, Jul 2008]

Submissions by phenotype
not specified Benign:1
Benign, criteria provided, single submitter | clinical testing | GeneDx | Aug 22, 2014 | 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. - |
FBN2-related disorder Benign:1
Likely benign, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | May 02, 2019 | This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). - |
Familial thoracic aortic aneurysm and aortic dissection Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 18, 2018 | 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. - |
