Figure 2. SCN5A Sequencing Results of the Familial Cardiomyopathy Registry.
(A) Chromatograms demonstrating heterologous peaks in nucleotide sequence. For this report, samples manifesting abnormal elution profile on the WAVE system were sequenced, and 4 new missense mutations were identified among our dilated cardiomyopathy (DCM) population. (B) Relative locations of all currently reported DCM missense mutations of SCN5A superimposed on a schematic of the SCN5A protein (7,8,10). Red denotes 5 total missense mutations identified within the Familial Cardiomyopathy Registry, including the 4 new mutations reported here and D1275N identified previously (7).
