Altered nucleotides are in capital letters, flanking nucleotides in lowercase. Numbers indicate nucleotide position of change, relative to the start site of the coding region (protein-coding genes) or mature RNA (rRNA genes). For protein-coding genes, the codon containing the change is given. Letters within parentheses are single-letter amino acid codes. “P” indicates that the gene is present in identical form. The number of base pairs in each coding region (whole gene or exon) is given.
