Personality traits in women with Turner syndrome

Turner syndrome is caused by the total or partial absence of, or structural abnormalities in, one sex chromosome. A personality style characterized by traits related to low neuroticism and high extroversion has been reported for females with Turner syndrome, indicating possible genetic factors related to personality development. This study examines personality traits in 37 Swedish women with Turner syndrome using the Karolinska Scales of Personality Inventory. Compared to reference data, the subjects rated themselves as more sensation seeking, less detached, less verbally aggressive and less irritated. These results partially support previous findings. The subjects were divided into three karyotype groups: 45,X (n = 13), 45,X/46,XX or 45,X/45,XY (n = 13), and structural abnormalities (n = 11). Contrary to some previous findings, no differences in personality were found between the karyotype groups.
