About this trial

This observational 'recruit by genotype' study aims to provide insights into the cellular and molecular pathways underlying beta cell disorders and their physiological consequences. Eligible individuals are those with and without a pathogenic genetic variant, acting as case and control, respectively. Using a "recruit by genotype" approach, the researchers will perform detailed and specific analysis according to the individual's genetic variant.

The study's main aims are to : 1) identify and describe biomarkers and cellular features in blood samples that occur because of the rare causal genetic variant; 2) study the altered physiology or cellular function that are due to the rare causal genetic variant.

Participants will attend a study visit that will entail:

* Consent * Data collection * Height and weight measures * Blood samples * MRI (optional), dependent on genotype and sub-study objectives.

There is no treatment and the participants' normal clinical care will be unaffected and will continue uninterrupted.

A small subset of participants may be invited for further sub-studies in the future. Researchers may recruit sex-matched healthy controls (without the variant of interest) with similar age and BMI (age: +/-15%, BMI: +/- 3 kg/m2) for specified case-control studies.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Mental capacity to give informed consent

Of any sex, ethnicity, location.

Group 1: Cases will have a genetic variant(s) resulting in a beta cell disorder.

Group 2: Controls will not have a genetic variant(s) resulting in a beta cell disorder and will be matched to a Case for sex, age (+/- 15%) and BMI (+/- 3 kg/m2).

Disqualifiers

Lack of mental capacity to give informed consent

Age <6 years; >99 years

Cochlear Implant

Aneurysm Clips

Trial population

Participants will be selected based on: 1. having a confirmed disease-causing genetic change that results in a beta cell disorder; 2. or being a suitably matched control (same sex; age +/- 15%; BMI +/- 3 kg/m2).

Trial outcomes

Primary outcomes

1

Identification and description of biomarkers or cellular features associated with specific rare causal genetic variants.

Study of cellular features (assessing gene and protein expression by relevant methodologies, including RNA sequencing and Flow Cytometry) in blood samples that occur because of the rare causal genetic variant.

Time frame

2

Identification of alterations in physiological function with specific rare genetic variants.

Study of the altered physiology (assessed by magnetic resonance imaging) or cellular function (biochemical assessment of pancreatic hormones/enzymes) that are due to the rare causal genetic variant.
