| Abstract: | Even though mutations in LMNA have been reported in patients with typical dilated cardio-myopathy(DCM)and atrioventricular block(AVB)previously,the purpose of this study was to disclose this novel genetic abnormality in one Chinese family with the atypical phenotype of progressive AVB followed by DCM with normal QRS interval.Genome-wide linkage analysis mapped the AVB gene in this family to a marker at chromosome 1q21.2,where the LMNA gene was located.Direct DNA sequence analysis revealed a heterozygous G t... |
