A Canadian father recently found out that his liver is a match for his twin daughters, but he can only use it to save one of them. 

Michael Wagner's 3-year-old twins, Binh and Phuoc, who were adopted from Vietnam, both suffer from a rare genetic disorder called Alagille syndrome. The syndrome effects their livers, and without a transplant, they will die, reported the Huffington Post. 

Wagner and his wife can't decide which one of their baby girls will get the potentially life-saving kidney, so they are leaving the decision up to Toronto General Hospital if they cannot find another match. 

"We told them we didn't want to be burdened with the decision making," Johanne Wagner, Michael's wife, told HuffPost.

Instead, the Wagner's set up a Facebook page for the twins with hopes of using social media to find a match for their daughters. 

According to the Facebook page, a potential live liver donor must be someone older than 18 years of age and younger than 60 years of age, be in good overall health and physical condition, have a compatible blood type: A or O (rhesus factor + or - does not matter) and have a BMI of less than 35 to be worked up for consideration and no greater than 32 at the time of surgery (transplant).

A liver transplant doesn't guarantee the girls will live a long, healthy life, but it will help expand their life expectancy, reported HuffPost. 

But despite the circumstances, the family doesn't show any negative feelings towards the adoption. 

"We look back and we have no regrets," Johanne Wagner told HuffPost. "We would travel this path all over again. They have taught us openness, they have taught our children sharing and openness. It's been nothing but a wonderful mess."
