• fragile-x syndrome [~50% | 1:4K | weight: 0,0008]
• Ehler-Danlos syndrome [?% | 1:5K | weight: ?]
• Marfan syndrome [?% | 1:6K | weight: ?]

Quick summary:
double jointed thumbs usually represents an inconvenient but harmless condition not associated with any sort of disorder (only in a small minority it represents a feature for one of the 4 listed medical conditions).
[In every 100 double-jointed thumbs cases in the general population (GP) you can expect to find about
10 joints hypermobility syndrome cases, etc.]
