简要总结
Bardet-Biedl syndrome (BBS; OMIN #209900) is a rare genetic disorder characterized by six core features: rod-cone dystrophy (retinitis pigmentosa), polydactyly, obesity, genital anomalies, renal anomalies, and learning difficulties. This study aims to contribute to genetic and medical knowledge of BBS, and to provide information on quality of life in adults with BBS and their close relatives. Participants will undergo medical assessments (ocular, oral, and physical examinations) and self-reporting of quality of life, diet, cognitive and emotional symptoms. There are some known genotype-phenotype associations in BBS and participants will be offered genetic testing. It is important to map both genotype and associated phenotype in order to provide optimal treatment and follow-up. Individuals with BBS, age 16 years or older, will be invited to participate. The investigators expect to enroll at least 25 male and female adults with BBS and 15 of their parents to participate in qualitative interviews. These interviews will investigate parents' experiences having a child with BBS, satisfaction with health care services, experience with social and family life, and psychological health.
详细描述
Improved care for adults with BBS living in Norway necessitates increased knowledge of pertinent health-related, emotional, and educational, employment and psychosocial issues. Adults with BBS living in Norway may face new challenges and have unmet healthcare needs. Therefore, the investigators intend to evaluate the adult with BBS as a person with special needs (e.g. need for support systems, lack of social opportunities, and mental health problems) and long-term challenges.This project will describe the visual, medical, physical, nutritional, and psychological difficulties experienced by people with BBS. The planned multi-disciplinary clinical evaluation in this study can help address the existing knowledge gaps. Relatives who help their loved ones with various activities of daily living may experience reduced quality of life and altered social roles. Therefore, the investigators also want to study the quality of life and psychological status of close relatives. This project might contribute information for new clinical protocols and suggest areas for further research in genetics, healthcare needs and quality of life for people living with BBS.

入选标准
- •Individuals diagnosed with BBS (see below), age 16 years or older. BBS is characterized by six core features : rod-cone dystrophy (retinitis pigmentosa), polydactyly, obesity, genital anomalies, renal anomalies, and learning difficulties.
- •Additional features include speech delay, developmental delay, diabetes mellitus, dental anomalies, congenital heart disease, brachydactyly (shortening of fingers/toes), ataxia, and anosmia/hyposmia (deficienct sense of smell). A minimum of four of the core features, or three core features and two additional features are required for the clinical diagnosis of BBS.
排除标准
- •Individuals age < 16 years, current severe illness or known diagnosis of autism.
结局指标
主要结局
The Medical Outcome Study 36-item Short Form Health Survey (SF-36)
时间窗: Feb 2022-Dec 2026
Health related quality of life (HRQOL) including measures of Physical and mental HRQOL. The SF-36 is a generic quality of life scale which has been validated in Norway. SF-36 evaluates eight domains of health: physical functioning, role limitation due to physical problems, bodily pain, general perception of health, social functioning, role limitations due to emotional functioning, vitality and mental health. Items on each scale are summed to yield a score from 0-100. A higher score means better quality of life. A license from Quality Metric is used for scoring (License number QM051240). The eight domains are summarized into physical component summary scores and mental component summary scores.
Needs and Provision Complexity Scale
时间窗: Feb 2022-Dec 2026
Presence of health care needs. This is an interview that evaluates the needs for healthcare and social support services. It has two parts: Part A (Needs) is completed by the clinician to evaluate each patient's need for health and social care; and Part B (Gets) is to evaluate to which these needs are met through the services that have been provided, based on information provided by the patient and a close relative. Each part includes 15 items with a total scoring range of 0-50 covering low and high levels of needs. There are six subscales representing two domains: Health and personal care needs, and Social and support needs. This scale was developed in the UK for neurological conditions and has been translated and used in Norway.
Behavioral Rating Inventory of Executive Function- Adult Version
时间窗: Feb 2022-Dec 2026
Assessing cognitive problems. BRIEF-A is a measure of everyday executive functions using self-reports. It includes 75 items that assess nine aspects of executive functioning symptoms of everyday life. Raw scores are transformed into age-corrected T-scores. Higher T-scores mean better executive function.
