Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Mar 26, 2012 | The Pro840Leu variant (FBN1) has not been reported in the literature nor previou sly identified by our laboratory. This amino acid residue is not conserved acro ss mammals (orangutan has an alanine at this position) suggesting a change at th is position could be tolerated and computational analyses (biochemical amino aci d properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide stron g support for or against an impact to the protein. However, this information is not predictive enough to rule out pathogenicity. Therefore, additional informat ion is needed to fully assess the clinical significance of the Pro840Leu variant . - |
