"dermatoglyphic observations in an iranian girl affected with congenital cutis laxa (autosomal recessive)"

the aim of the this work was to determine the finger patterns, finger ridge count (frc), total finger ridge count (tfrc), and asymmetry of finger ridge count (afrc) of an iranian girl (aged 13 years) affected with congenital cutis laxa (ccl).the fingerprints of the first phalanx of both hands were taken by using the standard method (stamp ink). the fingerprints were classified according to the galton nomenclature. the patterns of palm creases were also studied. besides, the ridges of fingerprints of all ten fingers were counted, then employing the related formulas, the frc, tfrc and afrc were calculated.results showed that the finger patterns of all ten fingers were radial loop; the major creases of the palms existed but their sizes were not normal. tfrc, which is the sum of all ten frcs, was 77 (“low”), and afrc was 10.344, more than that of her normal sister, that was 7.280. it is concluded that in ccl, the tfrc and symmetry of the fingertips ridges count may decrease; also palm pattern may be unusual.
