GeneDx RCV000196420 SCV000250187 uncertain significance not provided 2018-03-16 criteria provided, single submitter clinical testing The G1094E variant of uncertain significance in the FBN2 gene has not been published as pathogenic or been reported as benign to our knowledge. The G1094E variant is not observed in large population cohorts (Lek et al., 2016). The G1094E variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Furthermore, in-silico analyses, including protein predictors and evolutionary conservation, support a deleterious effect. Nevertheless, although G1094E resides in a calcium-binding EGF-like domain, it does not affect a Cysteine. Cysteine substitutions in the calcium-binding EGF-like domains represent the majority of pathogenic missense changes associated with FBN2-related disorders (Collod-Beroud et al., 2003; Frédéric et al., 2009).
