  • Title: Data on heteroplasmic mutations in mitochondrial genomes of loggerhead and hawksbill sea turtles: First approach.
    Author: Delgado-Cano D, Mariño-Ramirez L, Hernández-Fernández J.
    Journal: Data Brief; 2020 Feb; 28():104882. PubMed ID: 31867420.
    Abstract:
    The populations of loggerhead (Caretta caretta) and hawksbill (Eretmochelys imbricata) sea turtles are suffering an exponential decline due to anthropic and environmental actions that threaten their survival. In these turtle populations, the degree of heteroplasmic mutations commonly related with pathologies, has not been studied. In this data report, the specifications of each heteroplasmic site (region, mutation, length) and the percentage of heteroplasmy of each gene for four mitochondrial genomes of turtles (loggerhead: Cc1, Cc2, Cc3 and hawksbill: Ei1) are presented. The highest value of heteroplasmy in tRNA was of 83.33% for the Cc2 turtle (tRNASer gene), in protein coding genes was 38.62% for Cc2 (ND5), and in rRNA genes of 0.74% for Ei1 turtle (rRNA-16S). The variability data obtained will be useful for further conservation projects, evolution studies and population health of these species. This is the first study of heteroplasmy in complete mitogenomes of loggerhead and hawksbill turtles.
