I have looked at the Kazusa pages for codon frequency tables, but find nothing for human mitochondrial (MT) genes. Thus, does anyone know of a source where I can see the frequency with which each codon is used in genes encoded by the human mitochondria? Searches of the internet and literature turn up genetic code tables, this codon = this amino acid and so on, but no frequencies.
I am trying to assess the consequences of synonymous SNPs in protein-coding MT genes, to see if the SNP alleles change from a rarely used to frequently used tRNA, for example. This could have consequences on translation rates.
