Résumé

Congenital disorders of glycosylation (CDG) are a group of rare metabolic diseases with heterogeneous presentations, leading to substantial diagnostic challenges, which are poorly understood. Therefore, this study aims to elucidate this diagnostic journey by examining families' and professionals' experiences. A questionnaire was designed for CDG families and professionals, garnering 160 and 35 responses, respectively. Analysis revealed the lack of seizures as a distinctive feature between PMM2-CDG (11.2%) with Other CDG (57.7%) at symptom onset. Hypotonia and developmental disability were prevalent symptoms across all studied CDG. Feeding problems were identified as an early onset symptom in PMM2-CDG (Cramer's V (V) = 0.30, False Discovery Rate (FDR) = 3.8 × 10 This study emphasizes the crucial role of community-centered research, and the insights families can offer to enhance CDG management. By pinpointing existing gaps and needs, our findings can inform targeted interventions and support systems to improve the lives of those impacted by CDG.

BACKGROUND BACKGROUND
Congenital disorders of glycosylation (CDG) are a group of rare metabolic diseases with heterogeneous presentations, leading to substantial diagnostic challenges, which are poorly understood. Therefore, this study aims to elucidate this diagnostic journey by examining families' and professionals' experiences.
RESULTS AND DISCUSSION CONCLUSIONS
A questionnaire was designed for CDG families and professionals, garnering 160 and 35 responses, respectively. Analysis revealed the lack of seizures as a distinctive feature between PMM2-CDG (11.2%) with Other CDG (57.7%) at symptom onset. Hypotonia and developmental disability were prevalent symptoms across all studied CDG. Feeding problems were identified as an early onset symptom in PMM2-CDG (Cramer's V (V) = 0.30, False Discovery Rate (FDR) = 3.8 × 10
CONCLUSION CONCLUSIONS
This study emphasizes the crucial role of community-centered research, and the insights families can offer to enhance CDG management. By pinpointing existing gaps and needs, our findings can inform targeted interventions and support systems to improve the lives of those impacted by CDG.
