Recently, a white baby girl Nmachi Ihegboro's arrival amazed genetic experts, as she was born to black parents.
However, she was not the first case. Another black couple were left stunned when they first saw their newly born son three years ago - he too was white.
The baffled couple have still not managed to find an explanation for the genetic mix-up three years after the youngster, Emmanuel, was born.
The baby girl is to undergo full genetic tests after doctors said the odds of her white colouring were "between many millions to one and a million to one."
Emmanuel - whose both the sisters are black - had left his parents dumbstruck.
"It is something genetic but we don't know what," the Sun quoted Dad Ethelbertas saying.
Mum Nkemakonam, 34, also said nurses gathered round in amazement when she gave birth to Emmanuel in February 2007.
Neither five-day-old Nmachi, of Woolwich, South London, nor Emmanuel, who lives in Middlesbrough, is albino.
