The Simian Line & it’s potential implications! - INTRO (1/14): About the single palmar transverse crease & the impact of a (harmless) minor physical anomaly - According medical science the ’single palmar transverse crease’ - a.k.a. simian line - is basically recognized to represent an inborn (harmless) minor physical anomaly, which typically starts developing during the 3rd month of pregnancy. What are the potential implications? Simian lines have a higher prevalence among asians, but a simian line in both hands is usually seen in not much more than 1% among caucasians. Hand reading experts claim that a simian line bares significance for the personality in an individual; however, is this a valid claim? This article presents a summary of the core aspects and most common issues involved with simian lines. This article presents a summary of the core aspects and most common issues involved with simian lines. Let’s take a look at how a simian line can be recognized properly, and what are the implications of a (harmless) minor physical anomaly?

However, in a ’complete simian line’ there is only a single crease present, leaving the impression that something appears to be missing! How to recognize simian lines? The concept of the classic simian line can be recognized to represent a ’complete’ fusion between the two horizontal palmar creases (heart line & head line), leaving the presence of a single line that is featured with the impression that something appears to be missing (see the right picture below leaving the impression of a single line). More details in the section: How to recognize simian lines? Why the name ’simian line’? The name ’simian line’ origins from the fact that the term ’simian’ is a synonym for ’primate’; in the hands of primates it is normal to see a single crease (or multiple creases) transversing the full palm’. Today, researchers & experts in science often prefer to use other names to describe simian lines, merely because of the ’primate’ connotation. More details in the section: Why the name Simian Line ? History of the simian line! In 1877 Pierre Paul Broca (a French physician, anatomist and anthropologist) introduced the ethnic aspect of palmar creases in anthropology. Back then he already pointed out that simian lines occurs in about 1-2% of Europeans, while it can be observed in more than 10% of some Asian populations. A few decades later, in 1906 R.L. Down described the medical significance of the simian line as a diagnostic marker. His report described the relationship between the simian crease and Down’s syndrome. But it took many years before the signifance of his observations were generally recognized in medical science, for until 1959 (when J. Lejeune discovered that the syndrome results from an extra chromosome: trisomy 21) Down’s syndrome was not yet recognized as a unique disorder. Much later, e.g. Kimura (1991) found in prenatal studies based on the hand developement in embryos that the simian line typically starts developing not before the second half of the 3rd month of pregnancy; though it might then still take a few more months before a full simian crease is formed. More details in the section: History of the simian line! Ethnicity & the simian line! The prevalence of simian lines varies significantly around the world due to a genetic factor that is associated with ethnicity. Among ethnic populations the highest prevalence is found in African Efé pygmies (a population that belongs to the smallest groups of people in the world). Interestingly, there are also many other types of genetics involved with simian lines. For example, a comparison between males and females around the world shows that males typically have a 50% higher prevalence of simian lines (compared to females). More details in the section: Ethnicity & the simian line! Health & the simian lines! Beyond ethnicty and sexe, other genetic factors can become involved with the development of a simian line (during prenatal development). During the 20th century the simian line became linked with a ’rainbow’ of syndromes, diseases & other medial problems . A quick summary of the effects seen in major diagnostic themes: • Simian line is 20x more common in Edwards syndrome • Simian line is 15x more common in Patau syndrome • Simian line is 10x more common in Down syndrome • Simian line is 5x more common in Fragile-x syndrome • Simian line is 3x more common in Diabetes Mellitus • Simian line is 3x more common in Schizophrenia • Simian line is 2x more common in low cognitive efficiency • Simian line is 2x more common in Neuroticism high scorers • Simian line is 2x more common in Marfan syndrome • Simian line is 2x more common in Psoriasis • Simian line is 2x more common in Rheumatoid Arthritis NOTE: All numbers above are based on prevalence statistics relative to control populations, which are supposed to be representative for the general population. The simian line is known to have the highest prevalence in the so-called ’trisomy syndromes’, which represent a group of genetic disorders featured with an extra chromosome - this creates a so-called ’trisomy’ in one of the 23 chromosome pairs. The two most common trisomy syndromes represent in respective: - Down syndrome (trisomy 21) , where the prevalence of the simian line is usually reported to be around 40%; - Edwards syndrome (trisomy 18) , where the prevalence has been confirmed to be around 70% - which is higher than in any known human (sub-)population around the world....
