Life Beyond Childhood: Insight Into the Lived Experience of 91 Adults With KBG Syndrome Through an Online Patient/Caregiver‐Reported Co‐Produced Questionnaire

Purpose
KBG syndrome (KBGS) is a rare neurodevelopmental syndrome. We aimed to study the impact of KBGS in adulthood as reported by individuals with KBGS and their families/caregivers, thereby exploring aspects of everyday life underreported by healthcare professionals.

Methods
We co-produced an online questionnaire for adults with KBGS and their families/caregivers. Participants were recruited via the KBG Foundation, an American-based charity supporting individuals with KBGS and their families worldwide, and other international collaborators.

Results
There were 91 responses for analysis, across the age range of 16–86 years. Respondents described a range of living arrangements, education, employment, leisure activities, and relationships. A higher proportion of 45–54year-olds had achieved independent living skills such as driving and grocery shopping compared to the younger age groups. None of the participants who were experiencing seizures lived independently. We described high rates of psychiatric comorbidities, behavioral difficulties, sleep problems, seizures, visual and hearing problems, dental and skeletal issues, and a higher than expected cardiovascular and gastrointestinal burden of disease.

Conclusion
This study provides new insights into the everyday life of adults with KBGS, along with high rates of comorbidities that continue to impact quality of life into adulthood, with implications for medical care.
