Single transverse palmar crease

Single Transverse Palmar Crease

The Single Transverse Palmar Crease (STPC), also known as Simian Line or Simian Crease, is a single crease that extends across the palm of the hand, formed by the fusion of the two palmar creases (known in palmistry as the "heart line" and the "head line") that people typically have.

Pronunciation: /ˈsɪŋɡəl trænˈvɜːrs ˈpɑːlmər kriːs/

Etymology: The term originates from the Latin words 'singulus' meaning 'single', 'transversus' meaning 'lying across', 'palma' meaning 'palm of the hand', and 'creases' from the Old English 'crease' meaning 'a line or mark made by folding a pliable material'.

Characteristics

The STPC is often associated with some genetic disorders, such as Down Syndrome and Aarskog syndrome, but it can also be found in people with no other health issues. It is more common in males than females and is also more likely to occur in people of Asian descent.
