Definition[ edit ] A social construct or construction concerns the meaning, notion, or connotation placed on an object or event by a society, and adopted by the inhabitants of that society with respect to how they view or deal with the object or event. A major focus of social constructionism is to uncover the ways in which individuals and groups participate in the construction of their perceived social reality. It involves looking at the ways social phenomena are developed, institutionalizedknown, and made into tradition by humans. Origins[ edit ] In terms of background, social constructionism is rooted in " symbolic interactionism " and "phenomenology.
Subunit 6 of mitochondrial ATP synthase complex V is encoded by nucleotides of the mitochondrial genome. For a discussion of genetic heterogeneity of mitochondrial complex V ATP synthase deficiency, see There was perinatal asphyxia but the neonatal period was unremarkable. Investigations at the age of 5 years showed elevated lactic acid level in blood and cerebrospinal fluid.
No mutated mtDNA could be observed in any of the maternal tissues.
The authors commented that low levels of deleted mtDNA occur in oocytes and that point mutations may occur in oocyte mtDNA. De Coo et al. Prenatal diagnosis was technically possible; however, there were 3 major concerns: The tissue variation was investigated by analyzing 2 or more different tissues from a total of 18 individuals; no substantial tissue variation was found.
The age-related variation of the mutation was investigated by comparing the amount of both mutations in blood taken at birth and at a later age; there was no substantial change in the proportion of either mutation over periods of 8 to 23 years in 4 individuals studied.
In addition, White et al.
Prenatal diagnosis for mtDNA mutations has been hindered by an inability to predict accurately the clinical severity expected from a mutant load measured in fetal tissue.
After reviewing 44 published and 12 unpublished pedigrees, White et al. They related the severity of symptoms to the mutant load and predicted the clinical outcome of a given mutant load. They also used the available data to generate empirical recurrence risks for genetic counseling, which may be used in conjunction with prenatal diagnosis.
In 4 unrelated infants who presented with isolated hypertrophic cardiomyopathy and congestive heart failurewho later developed severe feeding difficulties and failure to thrive, Ware et al. The bioenergetic defects varied dramatically, not only among different ATP6 mutants, but also among lines carrying the same TG mutation.

Mutants with the most severe ATP synthesis impairment showed defective respiration and disassembly of respiratory chain complexes. Sequencing of the entire mtDNA from the different mutant cell lines identified variations in structural genes, resulting in amino acid changes that destabilized the respiratory chain.
Functional studies using a patient-derived skin fibroblast line showed a profound reduction in oligomycin-sensitive respiration compared to control, consistent with a defect in mitochondrial complex V function. Whole-exome sequencing of relevant nuclear genes detected no pathogenic variants.
As an alternative to drift, natural selection might have enriched for certain mtDNA lineages as people migrated north into colder climates.
To test this hypothesis, Mishmar et al. African mtDNA variation did not significantly deviate from the standard neutral model, whereas European, Asian, and Siberian plus North American variations did. ATP6 was highly variable in the mtDNAs from the arctic zone, cytochrome b was particularly variable in the temperate zone, and cytochrome oxidase I was notably more variable in the tropics.
Moreover, multiple amino acid changes found in ATP6, cytochrome b, and cytochrome oxidase I appeared to be functionally significant.
From these analyses, Mishmar et al.
