GeneDx RCV000181654 SCV000233957 pathogenic not provided 2013-08-05 criteria provided, single submitter clinical testing Although the c.2180dupG variant in the FBN1 gene has not been reported to our knowledge, this variant causes a shift in reading frame starting at codon Cysteine 727, changing it to a Tryptophan, and creating a premature stop codon at position 6 of the new reading frame, denoted p.Cys727TrpfsX6. This variant is expected to result in either an abnormal, truncated protein product or loss of protein from this allele through nonsense-mediated mRNA decay. Other frameshift variants in the FBN1 gene have been reported in association with Marfan syndrome. In summary, c.2180dupG in the FBN1 gene is interpreted as a pathogenic variant.
