Brief summary in lay language

A previous study provides evidence that boys and adolescents with Klinefelter syndrome (KS) have limited physical fitness/performance. We assume that this aspect is caused, among other things, by a dysregulation of the autonomic nervous system and want to investigate this further using several functional tests in this study. During a consultation and study-related examinations, a physical examination will be carried out and the hormone status will be determined. Pain perception will be assessed using a proven method to measure it, called Quantitative Sensory Testing (QST). In addition, the functions of the autonomic nervous system are measured by means of heart rate variability analysis. The participants also complete a performance diagnostic examination on a jumping plate as well as through a 6-minute walking test. If medically indicated, a lung function test is also carried out. The above-mentioned study-related measures require an additional time commitment of about 3 hours. The study is conducted at the University Clinic for Paediatrics and Adolescent Medicine in Bochum and is headed by Prof. Dr. med. Corinna Grasemann. Participation in the study has no influence on the medical treatment of the participants. Additional visits to the clinic are not required.

Brief summary in scientific language

Klinefelter syndrome (KS) is one of the most common chromosomal aberrations of the male sex and is characterised by the presence of an extra X chromosome in a male phenotype. With a prevalence of 0.1-0.2% in the general population, the syndrome is probably the most common chromosomal aneuploidy in humans. A heterogeneous presentation with multiple organ system involvement leads to a high proportion of underdiagnosed affected individuals. In a previous study, an impaired cardiorespiratory performance in the sense of an increased prevalence of chronotropic insufficiency was observed in adolescents with KS. Etiologically, a dysregulation of the autonomic nervous system is suspected. This hypothesis is supported by literature describing abnormalities of the nervous system in people with KS. The results of the study are needed to understand the cause of the previously detected reduced cardiorespiratory performance in patients with KS and to develop targeted therapy options.
