Correction: Complete Mitochondrial Genome Sequencing Reveals Novel Haplotypes in a Polynesian Population
Open accessAbstract
The high risk of metabolic disease traits in Polynesians may be partly explained by elevated prevalence of genetic variants involved in energy metabolism.The genetics of Polynesian populations has been shaped by island hoping migration events which have possibly favoured thrifty genes.The aim of this study was to sequence the mitochondrial genome in a group of Maoris in an effort to characterise genome variation in this Polynesian population for use in future disease association studies.We sequenced the complete mitochondrial genomes of 20 non-admixed Maori subjects using Affymetrix technology.DNA diversity analyses showed the Maori group exhibited reduced mitochondrial genome diversity compared to other worldwide populations, which is consistent with historical bottleneck and founder effects.Global phylogenetic analysis positioned these Maori subjects specifically within mitochondrial haplogroup -B4a1a1.Interestingly, we identified several novel variants that collectively form new and unique Maori motifs -B4a1a1c, B4a1a1a3 and B4a1a1a5.Compared to ancestral populations we observed an increased frequency of non-synonymous coding variants of several mitochondrial genes in the Maori group, which may be a result of positive selection and/or genetic drift effects.In conclusion, this study reports the first complete mitochondrial genome sequence data for a Maori population.Overall, these new data reveal novel mitochondrial genome signatures in this Polynesian population and enhance the phylogenetic picture of maternal ancestry in Oceania.The increased frequency of several mitochondrial coding variants makes them good candidates for future studies aimed at assessment of metabolic disease risk in Polynesian populations.

In the citing paper
“The two individuals with high DNA quality results included B4a1a1a3 and B4a1a1a, and two out of three mutations reported to be unique to modern Māori were found [89].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
