A white New Jersey couple who had a daughter through IVF were stunned when the baby developed “Asian features” — and a DNA test proved the husband was not the father, according to their lawsuit against the clinic.

Kristina Koedderich and Drew Wasilewski, who are now divorced, went to the Institute for Reproductive Medicine and Science at Saint Barnabas in 2012 and spent $500,000 for treatment, according to the court papers filed in Essex County Superior Court.

Their daughter was born in 2013 and “a couple years later, they noticed the baby started having Asian features,” the couple’s attorney David Mazie of Mazie, Slater, Katz & Freeman, told The Post.

A DNA test in 2015 confirmed that there was “0% probability” that Drew, 49, was his daughter’s biological father, according to the suit.

The clinic’s negligence caused “the breakdown of the marriage between Kristina and Drew Wasilewski,” claims the suit.

Superior Court Judge Keith Lynott last month ordered the clinic to hand over a list of men who donated sperm around the same time the couple used the facility — in the hopes of narrowing down who the girl’s biological father is.

The parents want to know whose sperm was used so they can learn about their now-6-year-old daughter’s genetic history — and in case she wants to have a relationship with her biological dad in the future.

“They love her very much, but it’s a very sensitive and very stressful situation for them,” Mazie said.

They also want to know if Drew’s semen was used for someone else’s IVF treatment.

The couple is seeking unspecified monetary damages, saying the clinic’s mistake caused “great pain, suffering, permanent injuries and disabilities, as well as the loss of enjoyment of the quality of life.”

Institute for Reproductive Medicine and Science spokesman Ronn Torossian said the clinic is “thoroughly examining the alleged incident.”

“The integrity of our treatment processes are paramount and we are taking this matter very seriously,” Torossian said.

The recent court order has “broad implications potentially affecting many more people than the immediate parties involved,” he added.

The amount the couple paid for their IVF was probably closer to 10 percent of the half-a-million they are claiming, the clinic said.

Last month, an Ohio couple who also went through IVF treatment filed a lawsuit claiming their clinic used a stranger’s sperm to father their now-24-year-old daughter.
