Applying newly devised model, heritability (VA/VP) of plasma uric acid level, corrected for age and sex and standardized, was estimated at 0.8 in families consisting of twin parents, spouses and children. Correlation between spouses due to common genotype (rho) was approximately 0.1, and variance due to common familial environment (VEC/VP) was -0.3. Analysis of families of selected twin children and their parents resulted in two estimates of heritability: approximately 0.7 and 0.3, rho being 0…

Relationship between blood uric acid level and personality traits.
TLDR
It is concluded that the plasma uric acid level and activity in a broader sense are under genetic control, consistent with the generally accepted view that persons with high uric Acid level are more active and energetic than those with low level.
Is it time to revise the normal range of serum uric acid levels?
TLDR
The findings strongly suggest to carefully reconsider the concept of "asymptomaticity" for chronic hyperuricemia and to revise the normal range of serum uric acid levels also considering the progressive worldwide increase of circulating levels of uric Acid, which could lead to a "shift to right" of normal range.
Uric acid: friend or foe? Uric acid and cognitive function "Gout kills more wise men than simple".
TLDR
Uric acid has a stimulating effect on the cerebral cortex, and this could have allowed humans to develop higher brain mass volume, better intellectual performances, and maybe evolutionary supremacy.
Uric acid and central nervous system functioning (a literature review)
TLDR
The present review finds that the enhancement of cognitive functions and motivations in hyperuricemia has been confirmed in different population samples, and the biochemical basis for such effects is the potential for uric acid synthesis in the central nervous system and the penetration of the blood-brain barrier by its precursors.
Uric acid and evolution.
TLDR
UA has protective effects against several neurodegenerative diseases, suggesting it could have interesting actions on neuronal development and function, and some, not so well-known, beneficial effects as an antioxidant and neuroprotector.
Hormonal and cytokine effects of uric acid
TLDR
Evidence is provided that uric acid has pro-inflammatory and proliferative effects on VSMC, and causes dysfunction of endothelial cells, and arteriosclerosis induced by hyperuricemia may be a novel mechanism for the development of essential hypertension.
Uric acid nephrolithiasis: proton titration of an essential molecule?

    Current opinion in nephrology and hypertension
  • 2006
TLDR
There is little doubt that uric acid serves multiple important functions in higher primates, however, it is also conceivable that this important molecule when present in the wrong concentration or context can lead to undesirable phenotypes.
Uric Acid nephrolithiasis: recent progress and future directions.
TLDR
A thorough review of the epidemiology and pathophysiology of uric acid nephrolithiasis is crucial for the diagnosis, treatment, and prevention of stones in patients with this condition.
Hyperuricemia-Related Diseases and Xanthine Oxidoreductase (XOR) Inhibitors: An Overview
TLDR
This review discusses the mechanism of uric acid homeostasis and alterations, updated prevalence, therapeutic outcomes, and molecular pathophysiology of hyperuricemia-related diseases, and summarize current discoveries in the development of new XOR inhibitors.

Plasma and urine uric acid levels: Heritability estimates and correlation with IQ
TLDR
Plasma and urine uric acid levels were measured in 37 pairs of twins aged 11 or 12 years and their parents and it was concluded that heritability of uric Acid level was not less than 0.3 in plasma and not more than 1 in urine.
Relative roles of genetic and environmental factors in the control of serum uric acid levels in normouricaemic subjects.
TLDR
It might be of interest, in view of the present controversy surrounding the genetics of gout and hyperuricaemia, to ascertain the strength of the genetic and environmental components in the control of the serum uric level in normouricaemic subjects.
Social Class Gradient of Serum Uric Acid Levels in Males
TLDR
Evidence for a social class gradient as reflected by occupation and education is presented and some degree of association of serum urate with intelligence and excellence of all-round performance is found, but not with social class of family of origin.
SERUM LIPIDS AND SERUM URIC ACID IN HUMAN TWINS.
TLDR
Demonstration that monozygotic twins do not form a homogeneous population focuses attention upon an unanswered question regarding the resemblance between twins which is deeply ingrained in twin studies but has received little recent attention.
Genetics of hyperuricaemia in Blackfeet and Pima Indians.
TLDR
The present study was undertaken to determine whether hyperuricaemia is, indeed, inherited, and, if so, what the mechanism of inheritance might be.
Serum urate concentrations in male high-school students.
TLDR
Evaluation of mean high-school grades among the three groups suggested that the AC group was more highly motivated to obtain further education, in spite of poor grades, and within this group, those who attended college for a longer length of time had higher SUA concentrations.
XV.—The Correlation between Relatives on the Supposition of Mendelian Inheritance.
Several attempts have already been made to interpret the well-established results of biometry in accordance with the Mendelian scheme of inheritance. It is here attempted to ascertain the biometrical
Serum urate concentrations among university professors; relation to drive, achievement, and leadership.
TLDR
The hypothesis that personal characteristics of drive, achievement, and leadership are positively associated with the level of uric acid in the serum is supported and the concept of serum urate as an endogenous cortical stimulant can also be supported.
Plasma uric acid concentrations among Edinburgh business executives.
TLDR
After assessing seven personality variables, surveying dietary habits, and studying the Gordon Personal Profile and Inventory of 100 executive level businessmen, it was found that only "Drive" and "Range of Activities" showed a significant positive correlation with plasma uric acid levels.
Origin of Man
OROWAN1 suggests that the high uric acid concentration in the blood of human beings and anthropoids, as compared with other mammals, may be a cause of their intellectual development. He holds that
