A three-year-old girl from Kingston, Ont., has received a liver transplant two months after her twin sister underwent the same surgery to combat a potentially fatal genetic disorder.

Twins Binh Wagner, left, and Phuoc have Alagille syndrome, which affects the function of their livers. (Wagner family/Canadian Press) A post on the Wagner family's Facebook page says Binh received her "gift" from an anonymous donor, though the timing of the surgery is being kept secret to protect the donor's privacy.

Binh's twin sister, Phuoc, returned home from hospital last month after receiving part of her father Michael Wagner's liver.

The girls suffer from Alagille syndrome, a genetic disorder that affects vital organs and can be fatal.

The family writes on Facebook that Binh is "recovering well, at her own pace," despite experiencing "very different medical issues" than her sister.

Phuoc, meanwhile, has managed to sleep without her feeding pump.

"We are looking forward to all being reunited and leading a healthier life now, with both transplants finally behind us," the post reads.
