Single palmar crease
Single Palmar Crease
The Single Palmar Crease (pronunciation: /ˈsɪŋɡəl ˈpɑːlmər kriːs/), also known as Simian Line or Simian Crease, is a feature of the human hand that is present in about 1 in 30 people. It is so named because it is a characteristic of many primates, or simians.
Etymology
The term "Single Palmar Crease" is derived from the Latin words 'singulus' meaning 'single', 'palma' meaning 'palm', and 'creare' meaning 'to create'. The term "Simian Line" is derived from the Latin 'simia', meaning 'ape', due to its prevalence in non-human primates.
Description
A Single Palmar Crease appears when the two major creases of the palm (the heart line and the head line) merge into a single line. This is a normal variation in hand structure, and it is inherited in a complex manner. It is more common in males than females, and can occur in one or both hands.
Medical Significance
While a Single Palmar Crease is often simply a normal variation, it can also be associated with certain medical conditions, such as Down Syndrome, Aarskog syndrome, Cohen syndrome, and Fetal alcohol syndrome. However, the presence of a Single Palmar Crease alone is not diagnostic of any of these conditions.
