Single transverse palmar crease
From Wikipedia, the free encyclopedia
In humans, a single transverse palmar crease is a single crease that extends across the palm of the hand, formed by the fusion of the two palmar creases that people typically have.[1][2] Because it resembles the usual condition of simian animals, it is also known as a simian crease or simian line, although these terms have fallen out of favor due to its pejorative connotation.[3]

The presence of a single transverse palmar crease can be, but is not always, a symptom of certain medical conditions such as Fetal alcohol syndrome and genetic abnormalities including Down syndrome and Noonan syndrome. Males are twice as likely as females to have this condition.
