This person was born with no middle joints in their fingers
Brachydactyly is a congenital disorder that causes someone’s fingers and toes to be substantially shorter than the average size compared to their overall body size. Sometimes, some bones from the fingers are missing. Some fingers or toes may be missing entirely; however, it can vary from person to person.
What is more, the majority of brachydactyly kinds are genetic, which means they can be handed down through generations since it is a dominant genetic trait. Furthermore, people with Down syndrome may also develop brachydactyly. In some cases, this condition may be caused by medications a mother takes while pregnant.
