Figure 2From: A G613A missense in the Hutchinson’s progeria lamin A/C gene causes a lone, autosomal dominant atrioventricular blockElectropherogram of the lamin A/C gene. Electropherograms of control (upper) and atrioventricular block-affected (lower) subjects showing heterozygosity for the LMNA/C mutation G613A in the latter. Heterozygosity is indicated by the presence of two peaks corresponding to G and A (arrow and magnification).Back to article page
