Introduction:
FOXP1 syndrome is a rare neurodevelopmental disorder due to forkhead box protein 1 (FOXP1) gene mutations and is associated with intellectual disability, dysmorphic features, and autism spectrum disorder. We aimed to assess body-focused repetitive behavior (BFRB) prevalence in this patient population using a cross-sectional survey-based study.
Methods:
A validated survey assessing for BFRBs was administered to parents attending the International FOXP1 Foundation conference on June 21, 2023, and was sent to a FOXP1 syndrome listserv.
Results:
Excoriation disorder, onychophagia, onychotillomania, and trichotillomania were reported by 58.6%, 38.6%, 29.7%, and 10.0% of subjects, with 63.4%, 59.3%, 54.5%, and 14.3% having moderate to severe disease, respectively. Overall, 28.6%, 30.0%, and 10.0% had one, two, and three BFRBs, respectively.
Conclusion:
Prevalence of BFRBs is high among FOXP1 syndrome patients surveyed, affecting quality of life for patients and their families and causing significant sequelae.
