No, not necessarily. There are many abnormalities that do not impede movement or bodily functions ... Like: Being born with 9 Fingers or toes .. If it does not disable normal use of the hands then it is not a disability.
Are physical abnormalities also disabilities?
I once knew a person with six fingers,
and toes. This is said to be the sixth cycle,
of creation.
Not necessary and a disability is when it keeps one from finding gainful employment for more than a year or longer
