GeneDx RCV000195816 SCV000250244 uncertain significance not provided 2012-11-05 criteria provided, single submitter clinical testing p.Asn2467Ser (AAT>AGT): c.7400 A>G in exon 58 of the FBN2 gene (NM_001999.3) The Asn2467Ser variant in the FBN2 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Although Asn2467Ser results in a conservative amino acid substitution of one polar amino acid with another, the Asn2467 position is conserved across species. In silico analysis predicts Asn2467Ser is possibly damaging to the protein structure/function. The NHLBI ESP Exome Variant Server reports Asn2467Ser was not observed in approximately 6,000 samples from individuals of European and African American backgrounds, indicating it is not a common benign variant in these populations. Nevertheless, no mutations in nearby codons have been reported in association with congenital contractural arachnodactyly, indicating this region of the protein may be tolerant of change. With the clinical and molecular information available at this time, we cannot definitively determine if Asn2467Ser is a disease-causing mutation or a rare benign variant This variant was found in TAAD
Invitae RCV002517178 SCV003450055 likely benign Congenital contractural arachnodactyly 2023-11-13 criteria provided, single submitter clinical testing
