Fig. 2From: A novel apolipoprotein E mutation, ApoE Ganzhou (Arg43Cys), in a Chinese son and his father with lipoprotein glomerulopathy: two case reportsDNA sequence analysis for ApoE mutation. ApoE gene was sequenced in genomic DNA from both patients (A, case 1; B, case 2) and a family member (C, mother of case 1). Both patients had a heterozygous ApoE mutation of C-to-T transition in exon 3 that changed the amino acid at position 43 of the mature protein from arginine to cysteine.
