Presenter Laura Ansell introduces the first episode of her BBC Sounds series DNA Trail: The Promise.

Billy from Brighton is in his 30s when he’s told by his mum Madeleine that the man who brought him up wasn't his ‘real’ dad.

Armed with only his name: William Anderson and the fact he served in the Royal New Zealand Air Force, Billy goes in search of his biological father. He tracks him down in the late 1970s but is rejected.

To listen to the rest of the series just search for DNA Trail on BBC Sounds.

A family's race against time to find the baby they believe DNA testing proves was switched at birth.

It’s the perfect gift for the person who already has everything. It promises to tell you who you really are, and how you’re connected to the world. A present that will reveal your genetic past – but could also disrupt your future.

In the second series of The Gift, Jenny Kleeman looked deeper into the unintended consequences - the aftershocks - set in motion when people take at-home DNA tests like Ancestry and 23andMe.

This included "Switched"; the stories of two women who discovered they had been accidentally swapped at birth in a West Midlands hospital in 1967– all due to an Ancestry DNA test, received as a Christmas gift.

As soon as the episode aired, people began to contact Jenny with tales of other incidences of accidental baby swaps - and one in particular stood out.

New episodes are available on BBC Sounds from Saturday 2 November, 2024.

October 6th, 2023 - the day before Hamas launches its attack on Israel - a data set stolen from at-home DNA testing company 23andMe is posted on the dark web. A hacker under the username Golem claims it contains millions of data points relating to Ashkenazi Jews living globally. A vast repository of 23andMe's account holder's personal information is then offered to anyone willing to pay for it - including names, birth dates, genetic ancestry and location details. Not only is it 23andMe's biggest ever security breach but apparently it's been motivated by racism.

Jenny Kleeman recently confirmed her Ashkenazi Jewish identity through a 23andMe test. Her mum and dad had done so a few years previously. In this bonus episode of The Gift, Jenny investigates the 23andMe breach to discover what happened, who was targeted and if information as sensitive as our genetic code - including her own - can ever be stored safely.
