About this study

Noonan syndrome (NS) is a rare genetic disease (incidence 1/2500 live births) characterized by the association of craniofacial manifestations, cardiopathies, short stature, and tumor predisposition. The genetic causes of Noonan Syndrome are mutations of genes involved in the Ras/Mitogen-Activated Protein Kinases (MAPK) pathway, mainly the gene encoding the tyrosine phosphatase Shp2 (50% of patients).Shp2 appears to be involved in many facets of energy metabolism control (glucose homeostasis, adipose tissue function…), through mechanisms that are poorly understood. Several metabolic anomalies (reduced adiposity, improved glucose tolerance) have been recently identified in an original mouse model carrying Shp2 mutation. Moreover, recent clinical survey has shown that adult Noonan Syndrome patients are protected from developping overweight and obesity when compared to the general population. However, the metabolic status associated with Noonan Syndrome condition has not been explored to date.

Read the detailed description

Differential hormone sensitivity is associated with Noonan Syndrome and participates in the development of some symptoms. The investigators have demonstrated that MAPK upregulation in Noonan Syndrome is responsible for partial growth hormone (GH) insensitivity, and subsequent growth retardation.

Clinical traits evocative of energy metabolism dysfunctions have been recently reported in Noonan Syndrome patients, although the origins and consequences of these metabolic changes have not been documented to date. The aim of this study is to explore the metabolic status of children with Noonan Syndrome.

Children with Noonan Syndrome will be compared with age- and sex-matched healthy children. The investigators hypothesize than Noonan Syndrome children have an increased insulin sensitivity compared to GHD children.

Study parameters will be collected including: clinical measurements (height, weight, body mass index, waist circumference, and blood pressure), glucose and insulin levels at baseline and after an oral glucose tolerance test (OGTT), body composition measured by dual-energy x-ray absorptiometry (DXA).

The study will include only one visit.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Oral Glucose tolerance testOther

    Oral glucose tolerance test (OGTT): glucose and insulin levels will be measured at time points 0, 90 and 120 min or 30, 60, 90 and 120 after 1.75 g/Kg (max 75 g) glucose administration depending of the patient weight.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Insulin sensitivity determined from the calculation of the Quantitative insulin sensitivity check index (QUICKI).

    Measured at the patient's arrival (TO) from the blood levels of glucose and fasting insulin

    Measured: T0 on an empty stomach

Secondary outcomes (8)
  1. Insulin sensitivity determined with HOMA index

    Glucose and insulin levels will be measured at time points 0, 90 and 120 min (children weigh 17-25kg) or 30, 60, 90 and 120 min (children weigh >25kg) after 1.75g/kg glucose administration (oral glucose tolerance test)

    Measured: T30, T60, T90 and T120 minutes after oral glucose tolerance test

  2. Blood pressure

    These tests will be done on arrival in hospital before the oral glucose tolerance test. Blood pressure is measured after 10 minutes of rest in the elongated child.

    Measured: T0

  3. Blood level of hemoglobin A1c and ghrelin

    Blood sample realised at T0 before the oral glucose tolerance test.

    Measured: T0 on an empty stomach

  4. Body composition as fat mass and muscle mass measured by dual-energy x-ray absorptiometry (DXA)

    This test will be realised during hospitalisation day, except if it has been done up to 6 months prior to enrollment.

    Measured: T0

  5. Body mass index

    This test will be realised during hospitalisation day, at patient arrival.

    Measured: T0

  6. Waist circumference

    This test will be realised during hospitalisation day, at patient arrival.

    Measured: T0

  7. Blood level of leptin

    Blood sample realised at T0 before the oral glucose tolerance test.

    Measured: T0 on an empty stomach

  8. Blood level of ghrelin

    Blood sample realised at T0 before the oral glucose tolerance test.

    Measured: T0 on an empty stomach

Questions about this trial

What is this clinical trial studying?

A study testing Oral Glucose tolerance test in people with Child Syndrome, run by University Hospital, Toulouse at 1 site in France.

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 2 inclusion and 3 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 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

What does the primary outcome measure?

Insulin sensitivity determined from the calculation of the Quantitative insulin sensitivity check index (QUICKI). (time frame: T0 on an empty stomach). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02383316, 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 Dec 2025.
