Before starting the survey, read the following information and instructions carefully


Why PMM2-CDG?

1) PMM2-CDG is characterized by a huge array of symptoms, often affecting multiple body
systems, influencing PMM2-CDG patients' quality of life (QoL).
2) There are no specific tool to measure QoL in any CDG type.
3) PMM2-CDG is the most frequent CDG type and, thus it can be used as a pilot.

AIM: This short survey aims to identify the clinical manifestations and factors that most affect
PMM2-CDG patients' QoL.

Why You and how can you help?
Because patients/families are THE EXPERTS! You're part of this community and, therefore, you represent
the voice of the patients. Therefore, please answer this anonymous survey sincerely, according to your experience and to the best of your knowledge.

Time commitment: The questionnaire has 4 QUESTIONS and takes a maximum of 10 to 15 minutes to complete.

ATTENTION: Each of the 4 questions refers to a specific age range, which corresponds to a
different phase of development (infancy, childhood, adolescence and adulthood)

If you have any doubts, please contact the research team:
