Yes, some people are born with four fingers instead of the typical five. This is not the norm, but it's a condition that can occur due to various genetic and developmental factors.
Understanding the Conditions
Several conditions can result in a person being born with four fingers. These include:
-
Symbrachydactyly: This is a birth defect where fingers are short and/or fused together. A specific type, short-finger symbrachydactyly (Type 1), involves having all or most of a thumb and four fingers. These digits may be shorter than normal and have missing bones (phalanges).

Polydactyly: This is a condition where a baby is born with extra fingers or toes. While not directly resulting in only four fingers, it's a related condition showcasing the variability in digit development. [Source: Polydactyly | Boston Children's Hospital]
Other less common conditions or anomalies during fetal development can also affect the number of fingers. Individuals with certain genetic disorders might also present with fewer digits. Examples mentioned in provided links showcase individuals born with four fingers due to a missing middle finger. [Sources: Reddit posts about individuals born with four fingers].
Causes and Treatment
The causes of conditions leading to fewer than five fingers vary. Genetic factors often play a significant role. Treatment options depend on the underlying condition and its severity, ranging from surgery to manage digit length and function to prosthetic solutions.
