“…It is now in general use among biological as well as medical workers (Penrose, 1968;Meier, 1980). Since unusual dermatoglyphic features have been found in Down syndrome, clinical interest in this aspect has begun to focus on patients with various congenital disorders (Schaumann and Alter, 1976;Reed, 1981). Mulvihill and Smith (1969) critically reviewed previous findings, concepts, and hypotheses concerning the genesis of dermatoglyphics and summarized them from five viewpoints: 1) concurring interpretations in the literature; 2) results of primate studies; 3) theoretical mathematical reasoning; 4) evidence from embryological studies; and 5) observations of fingerprints in malformed hands.…”

The development of dermal ridges, ridge configurations, and volar pad contours was investigated in the volar skin of the rat (Rattus norvegicus). The ridged structures corresponding to the epidermal ridges of primates exist only at the epidermal-dermal junction in the rat. Dermal specimens were prepared by treatment with alkaline solution and examined by toluidine blue staining and scanning electron microscopy, together with histological sections. Differentiation of dermal ridges began on day 18 of gestation on the palm followed by the sole. Ridges increased in number with advancing age. The process was complete approximately 2-3 days after birth, and sweat ducts began to develop simultaneously. As dermal ridges present various configurational patterns on palmar interdigital pad III, pattern formation on this pad was inspected in fetuses of three inbred strains possessing different pattern types, and in the hybrid progeny derived from them. Patterns and pad forms appeared to be under genetic control. It was revealed that the ridge arrangements, i.e., whorls, triradii, comb-like patterns, and others, are closely related to the pad contours during the developmental period, as hypothesized in primates.

“…Dermatoglyphics has an important role in dysmorphology and should be used in conjunction with the physical examination rather than as an independent diagnostic test 6 when the patients present with chromosome abnormalities, aneuploidies and newly recognized deficiency and duplication syndromes. SC and the palmar flexion creases appear on the palms of the hands and soles of the feet and usually develop by the 12 th week of gestation in the fetus.…”

“…Hence, SC should not be used as an independent test to diagnose DS. 6 SC are also useful for diagnosing intrauterine toxin exposure, 3,17 fetal alcoholic syndrome, mental retardation, neoplasia, and other diseases. 14,19 A unilateral SC was also reported in the case of chromosome 9 mutation causing nevoid basal cell carcinoma syndrome and Robinow syndrome.…”

Simian crease (SC), a single transverse crease that extends from across the palm of the hand. The presence of a single transverse palmar crease or the SC can be, but not always, a symptom associated with abnormal medical conditions. In dysmorphology, the clinical significance of variability of palmar creases especially SC are widely recognized and have occurred more frequently in patients with various congenital anomalies that are caused by genetic as well as environmental insults in the first half of pregnancy. SC has been studied extensively in children especially with Down's syndrome (DS) where the incidence of SC is more than 63%. In this case report, two families are discussed with relevance to the presence of SC. The first family with two children with DS have no SC in any of them, whereas the second healthy family only the father who is a doctor by profession having an SC.

“…The location of the study was to allow for a good mixture of social background to allow for the inclusion of quantitative palmer variables. 26 All subject without Ijaw consanguinity was exclude, and where relationship existed among subjects, only the digital print of one was taken to avoid statistical distortion of occurrence of a particular feature in a relatively small sample. 1 Bilateral finger and palmer print were obtained using the Antonoks method 27 .The pattern configuration was classified according to Cummins and Midlo standard technique while the ridges were counted according to Holt method.…”

Introduction: Dermatoglyphics refers to the study of naturally occurring ridge on the planter surface of hand and foot of primates and other animals. Dermatoglyphics is a polygenic trait and is not duplicated among species even among monozygotic twins.The Ijaw’s are located predominately in the Niger Delta with fishing as their main stay of economy.Aim: To determine the frequency distribution and gender differences of dermatoglyphic patterns of the Ijaw ethnic group in Nigeria.Methodology: A total of 500 subjects were randomly selected to establish their digital and palmer dermatoglyphics by counting and classifying their ridge patterns based on standard technique.Results: The highest dermatoglyphic pattern frequency was radial loop (RL) 2.7±1.22, with least occurrence of ulnar loop pattern (UL) 1.37±0.60. There were no significant total finger ridge count (TFRC) and pattern intensity indices (PII) between sex P>0.05. Female subject had a significantly higher mean ATD angle and a-b ridge count than their male counterpart P <0.05.Discussion: There was a prevalence and elevated total frequency of radial loop and a diminution of whorl digital dermatoglyphic patterns; this finding is unique for this study population since most African studies among Nigeria ethnic group has ulnar loop as a predominate digital pattern. Also, sexual dimorphism was shown to exists in total finger ridge count (TFRC) and pattern intensity indices (PII) among the sampled subjects, however female subjects were reported to have higher mean ATD angle and a-b ridge count when compared to their male counterpart, this was statistically significant at P<0.05.Conclusion: This study has reported pattern frequency and gender asymmetry of digital and palmer dermatoglyphics traits of the Ijaw ethnic group.
