Trial summary

This study will elucidate how the parental origin of the X-chromosome influences health status as well as metabolic fate in Klinefelter patients. Epigenetics and transcriptome-research will be directly linked to the metabolic and inflammatory pattern of actual patients to improve care for them. Read more about this study

About this study

Official title: Klinefelter Syndrome: Do the Parental Origin and Epigenetic Profile of the Supernumerary X Chromosome Determine Phenotype, Morbidity, Inflammatory Status and Cardiovascular Risk?

This study will elucidate how the parental origin of the X-chromosome influences health status as well as metabolic fate in Klinefelter patients. Epigenetics and transcriptome-research will be directly linked to the metabolic and inflammatory pattern of actual patients to improve care for them. The Klinefelter Syndrome is one of the most common genetic disorders in men. The patients have one supernumerary X-chromosome, which is partly active and disturbs a normal male development. Testosterone deficiency in form of primary hypogonadism is a common feature in these men. Such a condition promotes clinically relevant metabolic patterns related to a pro-inflammatory status and diabetes mellitus type 2 (insulin resis-tance), cardiovascular disease as well as infertility. However, the variety of pathologies is pro-nounced between patients and low testosterone concentrations cannot fully explain the wide scope of pathologies in these men. Some patients become clinically obvious during puberty and adoles-cence, some in their thirties or later and all exhibit a huge variation in phenotype. Switching on and off of specific genes on the X-chromosome is differential, depending on the origin either from the maternal or paternal side. Hence, an influence on the clinical picture is hypothesised. Thus, key targets are clarification of the parental origin of the supernumerary X chromosome and elucidation of methylation and expression profile of pivotal X-chromosomal genes. These will be related to clinically relevant metabolic and inflammatory patterns as well as fertility to identify individual risks as well as treatment strategies for Klinefelter patients.

Questions about this trial

What is this clinical trial studying?

An observational study of Klinefelter Syndrome, Hypogonadism, run by University Hospital Muenster.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Oct 2012. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01703676, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Oct 2012.
