GeneDx RCV000196103 SCV000250190 uncertain significance not provided 2012-11-05 criteria provided, single submitter clinical testing p.Arg1120Ser (AGG>AGT): c.3360 G>T in exon 26 of the FBN2 gene (NM_001999.3). The Arg1120Ser variant in the FBN2 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Arg1120Ser results in a semi-conservative amino acid substitution of a positively charged Arginine with a neutral, polar Serine at a position that is class conserved across species. Mutations in nearby codons (Asp1115His, Ser1120Pro) have been reported in association with congenital contractural arachnodactyly supporting the functional importance of this region of the protein. The NHLBI ESP Exome Variant Server reports Arg1120Ser 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. With the clinical and molecular information available at this time, we cannot definitively determine if Arg1120Ser is a disease-causing mutation or a rare benign variant.This variant was found in TAAD
