Two North Dakota men say a direct to consumer genetic test changed their understanding of their lives after revealing they had been switched at birth nearly four decades ago. Jeremy Morrison and Kyle Bylin, who were both born in 1988, are now suing Unity Medical Center in North Dakota while seeking answers about how the mix up happened.

The case came to light after Bylin received an at home DNA test as a gift two years ago. According to Bylin, the results showed no genetic connection to the family that raised him, setting off a search that ultimately uncovered the truth.

"It was absolutely mind-blowing," Bylin told Fox & Friends. "We knew the DNA trail didn’t make sense, but to find out you’ve been switched at birth is a huge revelation."

The DNA results instead identified a biological aunt. That discovery eventually led Bylin to her nephew, Jeremy Morrison, and additional DNA testing confirmed that the two men had been raised by each other's biological families.

According to the lawsuit, Morrison and Bylin were the only two babies born at Unity Medical Center in Grafton, North Dakota, on Jan. 26, 1988. The lawsuit alleges that the babies were switched after birth.

Morrison said he had long questioned why he looked so different from the woman who raised him. He recalled joking over the years about those differences while growing up.

"I kind of had a feeling inside that I was adopted or, you know, she stole me or something like that," Morrison said. Even so, he said he would not necessarily change what happened if he had the chance.

"It’s a little bit of nature, a little bit of nurture, and you end up with the life that you have," he said when asked if he’d go back and undo the switch.

Morrison also emphasized that the family who raised him remains his family despite the DNA discovery. "[My parents] will always be my parents. A DNA test isn’t going to change 38 years of memories overnight," Morrison said.

Bylin described the emotional impact of learning that he had been separated from his biological parents from birth. He said the discovery left him feeling that an important relationship had been lost.

"Do I feel like I lost the ability to truly connect with my biological parents ? Absolutely," Bylin said.

The two men filed a lawsuit against Unity Medical Center alleging emotional distress caused by negligence and medical malpractice. They claim the hospital deprived them of the lives they were meant to live because of the alleged mix up.

Unity Medical Center denied responsibility for the incident. The hospital said an internal review found no evidence that hospital personnel were responsible, although it did not dispute that the swap occurred.

"We recognize the profound impact this discovery has had on them and their families," the hospital said in a statement. "While we deeply sympathize with the men and their families, we have found no evidence to support claims that Unity Medical Center or its staff were responsible for what occurred."

Since learning the truth, both men have met their respective biological parents. However, despite their unusual connection, Morrison said he and Bylin have not yet met each other in person.

"There are no plans in the works right now," Morrison said. "I grew up with his entire family. And he grew up with my entire family," he added, as the reason the two men "don’t feel like" they need to meet.

As the lawsuit moves forward, both men said they are focused on continuing with their lives while also bringing attention to their experience. They said the discovery has permanently affected them and their families, but they are trying to move ahead.

"We’re just trying to raise awareness of this situation," Bylin added.
