Figure 4From: Challenges in the association of human single nucleotide polymorphism mentions with unique database identifiersIllustration of the recommendations using the genomic sequence. The example annotations for parts of the gene MECP2 (NG_007107.1) are following the genomic DNA numbering concept. Numbering starts at the beginning of the used reference sequence. Following bases are consecutively numbered. Using these recommendations the two SNPs are described as 4943C→A and 10490T→CBack to article page
