Figure 3 From: Sequence variation in human succinate dehydrogenase genes: evidence for long-term balancing selection on SDHA Haplotypes of SDHA. Periods denote the identical SNP variant when compared to the most common haplotype of each haplogroup. @NC = non-coding, S = synonymous coding, NS = non-synonymous coding. I = insertion allele, D = deletion allele. ^AA = African-American samples, EA = European-American samples.Back to article page
