Sienna Bernal and Sierra Bernal, 20-year-old from Tomball, Texas, are twins but one of them, Sienna, suffers from primordial dwarfism.
Sienna is the one that is from the disease (Dandy-walker syndromes, a health condition that causes abnormal brain growth) which makes her a foot shorter than her sister. She also wieghs only 90 pounds compared to her sister that weighs 98 pounds.
Sierra said thatwhenever people see both of them, they always ask them how old they both are from each other.
She added that even when they already told people that they are twins, they still ask them if they are of the same age.
