Hair Shed by Pet Cats is Useful Source of Forensic Evidence, Study Says

A single cat hair contains DNA which could link a suspect and a crime-scene, or a victim, according to a new study led by University of Leicester scientist Emily Patterson. While a human perpetrator may take pains not to leave their own DNA behind, transferred cat hair contains its own…

Targeted knockout of a conserved plant mitochondrial gene by genome editing

Plant material and growth conditions Nicotiana tabacum cultivar Petit Havana was used for all experiments. The TALEN design and the TALEN-expressing line Nt-JF1006-30 were described previously19. For plant growth under sterile conditions, surface-sterilized seeds were germinated on Murashige and Skoog (MS) medium52 consisting of premixed MS salts and modified vitamins…

Enhanced mitochondrial genome analysis: bioinformatic and long-read sequencing advances and their diagnostic implications

Introduction: Primary mitochondrial diseases (PMDs) comprise a large and heterogeneous group of genetic diseases that result from pathogenic variants in either nuclear DNA (nDNA) or mitochondrial DNA (mtDNA). Widespread adoption of next-generation sequencing (NGS) has improved the efficiency and accuracy of mtDNA diagnoses; however, several challenges remain. Areas covered: In…

Evidence of natural selection in the mitochondrial-derived peptides humanin and SHLP6

Our evaluation of synonymous codon bias has revealed that at least two MDPs, humanin and SHLP6, show evidence of natural selection, implying these peptides have biological roles that have been important during the course of vertebrate evolution. For humanin the synonymous codon bias analysis in vertebrates shows robust evidence of…

Nuclear genetic control of mtDNA copy number and heteroplasmy in humans

Overview of mtSwirl Here we develop mtSwirl, a scalable pipeline for mtCN and variant calling which makes calls relative to an internally generated per-sample consensus sequence before mapping all calls back to GRCh38. In addition to GRCh38 reference files and WGS data, the mtSwirl pipeline takes as input nuclear genome…

A meta-analysis and a functional study support the influence of mtDNA variant m.16519C on the risk of rapid progression of knee osteoarthritis

Introduction Osteoarthritis (OA) is a chronic musculoskeletal disease with a polygenic and heterogeneous nature that involves movable joints. The set of features that take place during the development of the disease lead to consider OA as a severe disease of the whole joint as an organ.1–3 The aetiology of knee…

Extensive mitogenomic heteroplasmy and its implications in the phylogeny of the fish genus Megalobrama

Megalobrama is China’s most economically valuable fish genera. Four species make up this genus: M. amblycephala (MA), M. terminalis (MT), M. pellegrini (MP), and M. hoffmanni (MH). Many researchers have investigated the genetic relationship of Megalobrama based on mitochondrial DNA (mtDNA) and discovered that the branches of the phylogenetic tree…

Multi-tissue landscape of somatic mtDNA mutations indicates tissue specific accumulation and removal in aging

Author Response Reviewer #1 (Public Review): The paper states that they observed a combined total of 77,017 single-nucleotide variants (SNVs) and 12,031 insertion/deletions (In/Dels) across all tissue, age, and intervention groups. Collectively, these data represent the largest collection of somatic mtDNA mutations obtained in a single study to date. However,…

Mitochondrial DNA variation across 56,434 individuals in gnomAD

Genomic databases of allele frequency are extremely helpful for evaluating clinical variants of unknown significance; however, until now, databases such as the Genome Aggregation Database (gnomAD) have focused on nuclear DNA and have ignored the mitochondrial genome (mtDNA). Here we present a pipeline to call mtDNA variants that addresses three…
