Palmar Flexion Creases Research Articles

Palmar creases in population studies.

Three strictly endogamous groups of Indian, Brahmin, Bhangi, and Punjabi Khattri, were analyzed to test the authenticity of palmar flexion creases as a criterion of human classification, according to the method of Bali and Chaube ('71), which has certain advantages over the existing classification. The significant frequency variation of palmar creases among different Indian populations and the bisexual and bimanual differences in the frequencies of different crease types indicate a regular distribution trend of the trait.

Dermatoglyphics in leukemia.

Extract: The study of dermatoglyphic features of 76 Caucasian patients with acute lymphocytic leukemia revealed that male patients had higher frequency of digital whorls (33%) than their brothers (26.7%) or fathers (27.8%). Patients with leukemia and their sibs had more Sydney palmar flexion creases (41.3% and 35.4%) than their parents (10.9%) or two control groups (20.4% and 10.5%). Speculation: The association of acute lymphocytic leukemia to increased frequency of digital whorl patterns and Sydney palmar flexion creases can now be tested prospectively. Confirmation of an association between leukemia and these dermatoglyphic features would indicate a relationship between prenatal characteristics and leukemogenesis.

Variation in palmar creases.

Unusual palmar flexion creases have been reported in a number of clinical syndromes including Down's syndrome, 1 trisomy D, 2 cri-du-chat, 3 and prenatal rubella. 4 These reports have awakened the interest of medical practitioners in a field formerly the province of chiromancers and gypsies. 5 Since palmar flexion creases develop in the embryo 6 and are readily evident at birth, the clinician may inspect them during the perinatal examination. If unusual configurations are present, he may be alerted to the possibility of other anomalies or his confidence in making an early diagnosis of a con genital defect may be strengthened. Systematic study of palmar creases reveals that some individuals who seem quite normal otherwise have unusual palmar flexion creases. Therefore, information on variation in palmar crease configuration in normal populations would

FINGERPRINTS AND PALM PRINTS (DERMATOGLYPHICS) AND PALMAR-FLEXION CREASES IN GONADAL DYSGENESIS, PSEUDOHYPOPARATHYROIDISM AND KLINEFELTER'S SYNDROME.

ALTHOUGH the heritability of the patterns on fingers and palms was pointed out by Sir Francis Galton1 in 1892 and soon put to wide use in physical anthropology, little agreement has been reached to date on the mode of inheritance of individual patterns and characteristics.2 3 4 5 6 7 Cummins and Midlo8 have summarized a substantial body of literature on this controversy in their comprehensive monograph, in which they review the comparative anatomy of fingerprints and palm prints and the incidence of individual dermatoglyphic traits in large numbers of people of different races. Palmar-flexion creases, which came to medical attention before fingerprints, have been . . .
