Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Exocrine pancreatic insufficiency leading to diabetes is a common hallmark of cystic fibrosis and cystic fibrosis related diabetes. Prevalence of glucose abnormalities in diabetes is a approaching 50% by the 2nd and 3rd decade of life in this disorder. The cystic fibrosis Foundation recommend screening for diabetes utilizing an oral glucose tolerance by the age of 10. Early diagnosis of diabetes in the syndrome as resulted in improved outcomes for patients with cystic fibrosis. It is my expectation that the prevalence of diabetes will be similar in SBDS patients. A small study performed I had the University of Cincinnati showed glucose abnormalities to occur in 5/20 individuals with the classic mutation.
Investigators propose to screen patients with the classic mutation for diabetes and endocrine disease utilizing continuous glucose monitoring over a 14 day period in addition to baseline fasting blood tests for insulin, GAD 65 antibody, Fructosamine, A1c and C peptide.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Study procedures include:
For participants with SDS:
obtaining informed consent/assent; obtaining medical \& medication history, including history of diabetes, review of medical records and lab results for confirmation of diagnosis and inclusion/exclusion assessment; performance of a standard oral glucose tolerance test (OGTT) to be performed at a center close to the participants home, a modified oral glucose tolerance test and a modified mixed meal tolerance test to be performed by participant at home with phone access to study staff for directions, blood draws performed at a local lab or local physician office or other medical center in close proximity to the participants home. Completion of on-line, or in the case of no computer access - paper, questionnaires completed by the participant/parent to collect medical and health history, parents/siblings will be asked to complete a health history, 3 day food diary completed by participant/parent; phone calls; wearing of blinded continuous glucose monitoring device for 14 days; medical records release, 3-day diet diary; Additional optional biological specimens to look at cell free DNA and future biomarkers of endoplasmic reticulum stress in the beta cells of the pancreas will be obtained and stored for future study Parent(s) and/or siblings if willing and consented, will complete on-line medical history questionnaire and provide medical record release.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
SDS - without Diabetes diagnosis
SDS - without Diabetes diagnosis
Oral Glucose Tolerance Test
This is a two step process. Subjects will be asked to fast overnight,(no food and only water to drink for at least 8 hours). Then when subjects arrive for the visit,participants will have blood drawn and be asked to drink a sugary liquid. One hour later, another blood sample will be drawn and after two hours a final blood sample will be drawn.
Modified Oral Glucose Tolerance Test
The participant will be asked to fast overnight (no food and only water to drink for at least 8 hours). There will be no blood drawn during this test, participant will be asked to drink a sugary liquid and to remaining fasting (water only) for the two hour after finishing the drink.
Modified Mixed Meal Tolerance Test
The participant will be asked to fast overnight (no food and only water to drink for at least 8 hours). The participant will be given a meal supplement to drink in place of breakfast, for example Boost Plus. The participant will be asked to drink the meal supplement and to remaining fasting (water only) for the next two hours.
Continuous Glucose Monitor
The participant will be provided a CGM device to wear for 10 days during the study period. The CGM will be blinded (meaning that the participant will not be able to see the results).
Food Diary
The participant will be asked to maintain a detailed food diary for 3 days during the 10 day study period.
Medical History Questionnaires
The participant will be asked to provide detailed medical history

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Age: 3 years of age and older to allow for baseline blood to be drawn. The Cystic Fibrosis group has seen glucose abnormalities well before age 10 but recommends screening after age 10. Investigators are attempting to define the population and will screen starting at age 3 to get a baseline data set.

* Able/willing to have a standard OGTT and modified OGTT
* Able/ willing to wear a Libre- Pro sensor and have sensor returned. If not willing to wear CGM- willing to do a standard OGTT as described.
* Not currently on diabetic therapy or labeled as diabetic.
* Willing to complete a health survey in regard to the SBDS and endocrine History
Population 2: SDS and Labeled as diabetic
* Age greater than 3

* Willing to provide consent/ assent and complete health survey for SBDS and endocrine history
