Brief Summary
The objectives of the study are to investigate if KCNQ1 mutation in Romano-Ward long QT patients can be associated with changes in insulin regulation and with psychological features of compulsivity, impulsivity and behavioural rigidity.

Study Arms (2)
KCNQ1 mutated subjects
EXPERIMENTALThis arm includes : * KCNQ1-mutated subjects with long QT Romano-Ward syndrome * KCNQ1-mutated subjects without phenotypic expression of the Romano-Ward syndrome * family relatives of a KCNQ1-mutated enrolled subject, carrying the KCNQ1 family mutation
Healthy subjects
SHAM COMPARATORHealthy subjects will be matched to KCNQ1 subjects. The matching factors will be age per decade (18-28 years, \> 28-38 years, \> 38-48 years), gender and body mass index (BMI: ≤ 24.9 kg/m2; 25-29.9 kg/m2; \> 30 kg/m2).
Interventions
The content of the assessment will be the same for all subjects and will consist of a cognitive assessment (attention, impulsivity) and a clinical assessment (impulsive behaviour, autistic traits,obsessive-compulsive behaviour).
A genome-wide association study (GWAS) will be performed for all subjects to search for associations between KCNQ1 mutations, insulin regulation and psychological features.
Fasted glycaemia and insulinaemia, glycated haemoglobin (HbA1c) and glycaemia following an oral glucose challenge test will be measured in all study subjects.
Eligibility Criteria
You may qualify if:
- In the investigator's opinion, the subject is generally healthy based on their medical records (subjects with KCNQ1 mutation only), medical history, physical examination, vital signs, body weight, ECG (except long QT if applicable), and based on the results of haematology, clinical chemistry, urinalysis, urine drug screen (UDS) and serology;
- Subjects with a KCNQ1 mutation: genotyped as having a mutation on the KCNQ1 gene with or without phenotypic manifestation of long QT syndrome;
- Relatives of subjects with a KCNQ1 mutation: KCNQ1-mutated family relatives (with or without phenotypic expression) of a subject carrying a KCNQ1 mutation (Romano-Ward patients or subjects without phenotypic manifestation of long QT syndrome);
- Relatives of subjects with a KCNQ1 mutation must live in a different household than the subject with the KCNQ1 mutation;
- All subjects: negative UDS by dipstick analysis: opiates, methadone, cocaine, amphetamines (including ecstasy), barbiturates, benzodiazepines, and cannabinoids at admission to the assessment visit;
- All subjects: negative alcohol breath test at admission to the assessment visit.
You may not qualify if:
- All subjects: having taken within 1 year before the assessment visit or currently taking any of the following medications: a. Antidiabetics: metformin, pioglitazone, acarbose, miglitol, sitagliptin, vildagliptin, saxagliptin, exenatide, liraglutide, semaglutide, repaglinide, nateglinide, insulin. b. Medications interfering with the central nervous system (CNS) such as any antipsychotic, antidepressant or regular use of anxiolytic medications \> once a week, or any attention deficit/hyperactivity disorder (ADHD) medication (e.g. methylphenidate);
- Healthy subjects and relatives of subjects with a KCNQ1 mutation not phenotypically affected: any of the following on a de novo ECG: a. Heart rate (HR) \< 40 bpm or \> 100 bpm; b. PR interval \<120 msec; c. Abnormal repolarization; d. QT interval corrected for HR using Fridericia's formula (QTcF) \> 450 msec for male subjects or \> 470 msec for female subjects.
