David Tennant reveals he has polydactyly with six toes on one foot

David Tennant has confirmed he has polydactyly, a condition where a person has extra toes. He has six toes on his right foot, which was first noted by fans online. Tennant described the extra toe as a small nubbin. Polydactyly is a common congenital condition affecting 1 in 500 to 1,000 live births. It can involve additional digits on hands or feet and may be inherited or caused by environmental factors during fetal development. Surgery is often not necessary unless the extra digit interferes with function. Families can choose to keep or remove the extra digit based on personal preference.
