This abnormality can affect the individual's physical abilities and dexterity, potentially impacting their overall wellbeing and quality of life. The reduced number of digits may lead to challenges in performing daily tasks that require fine motor skills, such as writing, grasping objects, or playing certain sports.

Though it does not typically pose a significant threat to overall health, oligodactyly can have a noticeable impact on the affected individual's ability to function efficiently in their daily activities.
