In an extraordinary case that defies remarkable odds of 200 million to one, NorthGene™ has successfully identified genetically identical triplets.

This is NorthGene™’s third case of genetically identical triplets in three years.

Louise and Gareth Davies, delighted parents, embarked on the path of genetic testing following a captivating revelation during the initial 12-week scan. The scan revealed that two of their triplets shared a placenta, while the third had its own, classifying the family under the category of a dichorionic triplet pregnancy.


What is a dichorionic triplet pregnancy?

A dichorionic triplet pregnancy means one baby has a separate placenta and two of the babies share a placenta. However, all three babies have separate amniotic sacs.

The attending Consultant hinted at the possibility of the triplets being identical, especially considering the shared placenta and their shared gender – all three being girls. The unique bundles of joy, Willow, Nancie, and Mabel Davies made their entrance into the world on November 10, 2023, at 34 weeks.

“Despite the initial observation by the surgeon that our newborns appeared different, we believed they looked identical. This is why we chose zygosity testing through NorthGene™ to determine whether they were indeed identical or not conclusively.” This decision stemmed from a desire for accurate medical records and to provide clarity for the girls’ future.

Upon receiving the results, the Davies family, from West Yorkshire, expressed overwhelming joy and delight. The revelation of having genetically identical triplets was described as nothing short of a miracle and a blessing.

“We are over the moon with the results. We couldn’t be happier to know that the girls are all identical. Thanks to NorthGene™ for conducting the testing; the process was straightforward, and we are relieved to have answers for the future.”

Support for triplets and multiples

The Davies family commended the supportive community of multiple parents on social media. They extended gratitude to Cardiff mother, Megan, who shared the details of NorthGene™.

NorthGene™ is thrilled to have played a pivotal role in providing answers for the Davies family and reaffirms its commitment to delivering cutting-edge genetic testing services while contributing to the scientific understanding of genetic variations in multiple births.

Charlotte Haskayne, Team Leader at NorthGene™, said, “We perform hundreds of DNA relationship tests daily, and while delivering unexpected news can be challenging, heartwarming cases remind us why we do what we do – making a positive impact in people’s lives.”

Shauna Leven, Chief Executive of Twins Trust, commented, “It’s fascinating to learn of three cases of identical triplets in three years at NorthGene™. It’s crucial for families to let the triplets develop their individual identities, from dressing them differently to dedicating quality time to each child when possible. This also involves careful consideration of their individual educational needs as they begin school. We wish all families well on their journey of parenting multiples.”
