Abstract

Psychogenetics of Ullrich-Turner syndrome (an investigation of 28 subjects and respective controls through the Bender test and Piagetian scales) (Psicogen�©tica da s�­ndrome de Ullrich-Turner (investiga�§�£o de 28 sujeitos com respectivos controles atrav�©s do teste de Bender e das escalas de Piaget))

Piagetian scales (PS) and Bender visual motor gestalt test (BT), as well as laterality and Ishihara tests, were applied to 28 subjects with universal 45,X Ullrich-Turner syndrome (UTS), and their respective controls, in order to investigate their cognitive performance. Dermatoglyphics were also analyzed to obtain “clues” of embryological changes that may have appeared during nervous system development and that could be associated with the cognitive performance of the UTS individuals. Statistical analysis was performed by parametric (descriptive statistics, t-test, t-test on paired data, and stepwise multiple regression analysis) and non-parametric tests (Fisher’s exact test, Spearman and Mann-Whitney). Dermatoglyphic pattern distribution was similar to that reported in previous studies of UTS individuals: ulnar loops (Lu) in the digital patterns and finger ridge, a-b, and A’-d counts were more frequent, while arch and whorl patterns were less frequent compared to controls. However, we did not find higher frequencies of hypothenar pattern, maximum atd angle, and ulnarity index in our UTS subjects, unlike other investigations. Furthermore, we found significant differences between UTS and control TI values.
