Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Mar 18, 2014 | The Phe6547Leu variant in TTN has not been previously reported in individuals wi th cardiomyopathy or in large population studies. Computational prediction tool s and conservation analysis suggest that the Phe6547Leu variant may not impact t he protein, though this information is not predictive enough to rule out pathoge nicity. Additional information is needed to fully assess the clinical significan ce of the Phe6547Leu variant. - |
