Fig. 5. Haplotype analysis identifies Arg47X as a hotspot mutation.

Fig. 5

a 15 AA patients heterozygous for the Arg47X variant (12-52799923-G-A; highlighted in pink). Different genotypes (blue = alternate homozygous, yellow = heterozygous, green = reference homozygous) at variant 12-52799341-C-T (582 bp away) confirms the presence of the Arg47X A allele on different haplotypes, identifying it as a hotspot mutation. b Schematic of KRT82 exon 1 (blue) with ENCODE methylation patterns (orange) in 4 skin cell types: fibroblasts (Fibrobl), Melanocytes (Melano), Neonatal Dermal Fibroblasts (NHDF-neo), and Skin Tissue (Skin BC). This is a visualization of the methylated cytosine (C) of the sense strand that is spontaneously deaminated resulting in a mutational hotspot and premature stop codon at position 47.
