This type of genetic syndrome is called Polydactyly.
For a family in Brazil being born with 12 fingers and toes is an asset and lucky that cause 14 members are all born with the same genetic abnormality.
The De Silva's from Brasilia, recently welcomed the youngest member into the clan, a baby boy born with the same genetic abnormality, The Sun reported.
In this family, having this abnormality is a unique mark and not something to be worried about.
This type of genetic syndrome is called Polydactyly. One out 1,000 people is born with the disorder.
"There are a variety of mutations that result in this condition but in the case of just having extra fingers and toes, then we’re looking at a misexpression of a gene which normally results in the patterning of your digits," Genetic Scientist, Dr Laura Lettice told The Sun. Adding, "If either your mum or your dad has extra digits, then you stand a 50/50 chance of getting the same type."
The De Silva’s are a thriving bunch and say they extra digits are an asset, that have made them better musicians and in sports.
