Fluctuating asymmetry, the random deviation from perfect symmetry, is a widely used population-level index of developmental instability, developmental noise, and robustness. It reflects a population's state of adaptation and genomic coadaptation. Here, we review the literature on fluctuating asymmetry of human populations. The most widely used bilateral traits include skeletal, dental, and facial dimensions; dermatoglyphic patterns and ridge counts; and facial shape. Each trait has its advantages and disadvantages, but results are most robust when multiple traits are combined into a composite index of fluctuating asymmetry (CFA). Both environmental (diet, climate, toxins) and genetic (aneuploidy, heterozygosity, inbreeding) stressors have been linked to population-level variation in fluctuating asymmetry. In general, these stressors increase average fluctuating asymmetry. Nevertheless, there have been many conflicting results, in part because (1) fluctuating asymmetry is a weak signal in a sea of noise; and (2) studies of human fluctuating asymmetry have not always followed best practices. The most serious concerns are insensitive asymmetry indices (correlation coefficient and coefficient of indetermination), inappropriate size scaling, unrecognized mixture distributions, inappropriate corrections for directional asymmetry, failure to use composite indices, and inattention to measurement error. Consequently, it is often difficult (or impossible) to compare results across traits, and across studies.

“…One of the factors that may contribute to the formation of genetic basis for the development of EH is polymorphism of angiotensin II type 1 receptor gene. In the studies carried out at the Department of Internal Medicine (medical faculty №2) of Vinnytsia National Pirogov Memorial Medical University, the relationship between combinations of finger patterns and variants of genotype of angiotensin II type 1 receptor gene was established among patients with ischemic heart disease and EH [8,10,15,18]. Currently characteristic features of dermatoglyphic fingerprints in individuals with no cardiovascular pathology, residents of Podillya region, have already been known.…”

Essential hypertension and its common complication - chronic heart failure, is one of the most significant medical, economic and social problems in the XXI century. At the same time, this pathology is 30-40% genetically predisposed. One of significant pathogenic factors is the inheritance of definite variants of genes, coding the receptors to angiotensin II type 1. For this reason, the effective and inexpensive researches for screening of the mentioned genetic phenomenon are being carried out. Objective: to improve the screening diagnostic methods for carriers of polymorphic genes of angiotensin II type 1 receptors with essential hypertension and essential hypertension complicated by chronic heart failure. There were studied dermatoglyphic prints of men 40-60 years, who are carriers of polymorphic gene variants of angiotensin II type 1 receptor with no cardiovascular diseases (n=79), male patients with essential hypertension and hypertrophy of the myocardium (stage II), II-III stages (n=62) and essential hypertension (n=50) complicated by chronic heart failure, residents of Podillya region of Ukraine. Genotyping of the gene of angiotensin II type 1 receptor was performed using polymerase chain reaction. All patients included in the control group and those with essential hypertension underwent dermatoglyphic examination of fingers on both hands using modern portable rolling scanner Futronic FS50 (Korea). Interpretation and decoding of dermatoglyphic prints was conducted by T. D. Gladkova’s method. Statistical analysis was done on personal computer using standard statistical package “STATISTICA 10.0”. The found ulnar loop was dominant dermatoglyphic print regardless of the presence or absence of essential hypertension and chronic heart failure in 40-60 year old men. Besides, positive correlation relationship was revealed between the inheritance gene of angiotensin II type 1 receptors and fingerprint patterns: the third finger on the left hand in males with no cardiovascular pathology (weak strength) and the second finger on the right hand in patients with essential hypertension (medium strength). In individuals with no cardiovascular diseases, carriers of genotype A1166A, prevalence of ulnar loop on the third finger of left hand is higher than in carriers of C allele gene of angiotensin II type 1 receptors. In males with essential hypertension, carriers of C allele, degree of incidence of the whorl on the second finger of right hand is significantly higher than in carriers of genotype А1166А, offering the possibility to determine the carriership of a particular gene of angiotensin II type 1 receptors. Carrying out dermatoglyphic examination in patients with an increase in blood pressure and determining the variant of carrier of the gene of the receptor to angiotensin II type 1 will make it possible to facilitate the selection of those individuals who in the future need to spend all the necessary amount of research to confirm the diagnosis of essential hypertension and the possible development of complications of the course of this cardiovascular disease.

“…It should be noted that the results are not always clear [59,62]. In some cases, researchers have noted that the markers of disorders in diseases may not be the actual FA level but rather the changes in the incidence and dermatoglyphic patterns [58,[63][64][65][66]. We tend to agree with Kaur and Batra [67] that clinical diagnosis should not be based on dermatoglyphic features alone, because, due to the great natural variation found in print patterns, no single feature is specific to a particular disease.…”

An ethnically homogeneous group of Yakuts (Mongoloid race, Northeast Asia), aged 18–31, was studied to characterize the diversity of particular features between left- and right-handed individuals. A total of 52 left-handed (32 women and 20 men) and 100 right-handed (50 women and 50 men) individuals were studied. Testing included two sets of questions and tasks, dynamometry of the right and left hand, and fingerprint analysis. Left-handed and right-handed people were found to differ in functional asymmetry of psychophysiological and motor reactions. Right-handers were characterized by higher intragroup similarity, while, among left-handers, greater dispersion of these traits was observed. Asymmetry in hand grip strength was less pronounced in the left-handed people than in the right-handed; this difference was statistically significant, and the difference was greater in men than in women. This suggests that the non-dominant hand in the left-handed people was subjected to a greater load and indicates the forced adaptation of the left-handed people to “dextrastress”. No significant difference between sexes was found when analyzing fingerprint patterns. Left-handers had arches significantly more often than right-handers. Radial loops were most often found on the index finger, and, in the left-handers, their occurrence was significantly higher on three to five fingers of the left hand compared with the right-handers. The levels of fluctuating asymmetry in left-handers and right-handers were similar.
