6/f/3p26.3 duplication (GDD, small stature). Unusually cold, sore, red, swollen hands in cold weather. Not improved upon warming near heater 30mins.

Not enough cases. I found only 2 other cases reported of a duplication of 3p26.3. One is from New Zeland. She sounds like she could use heated mittens in the cold--available at ski shops. Impossible to say whether it is related to the duplication. You could contact the authors of this publication--I'm sure that they would be fascinated to see her. http://www.hindawi.com/journals/crig/2014/295359/
