- WHAT IS SIMIAN LINE ON PALM? Everyone realizes that there are three primary lines in palmistry, to be specific life line, head line and heart line. For certain individuals, the head line and the heart line cover into a solitary line, which is known as the Simian Line, Simian Crease or Single Transverse Palmar Crease. As such, you possibly have two fundamental lines while others have three if a simian line shows up in your palm.
- Human hands develop palmar creases in the womb close to the 12th week of gestation. The palm typically has 2 of these creases. However, occasionally, the horizontal creases join together to form a single transverse palmar crease (STPC). An STPC used to be called a simian crease, however, the term is no longer considered appropriate.
- It’s where the head and the heart line are merged into a single line (sometimes called a Simian Crease). This usually means it’s hard to separate logic and feelings. It’s often associated with being a mystic, visionary, guru, or leader (best case) and a socially awkward outcast or crazy person at worst.
First of all, there is a pure simian line, or a partial one. If you have one line, straight across, with no evidence of any separate head and heart line, it's pure. If part of the line branches out to the head or heart area, that part is magnified. Alright, so basically, a simian line is when the head and heart lines merge. A crease on the palm of the hand, so called because of its similarity to the transverse flexion crease found in some monkeys. Normally the palm of the hand at birth contains several flexion creases, two of which are separate and approx. When these two appear to fuse and form a single transverse crease, a simian crease is present.
Single palmar crease; Transverse palmar crease; Palmar creaseA simian crease is a single line that runs across the palm of the hand. People usually have 3 creases in their palms.
The term 'simian crease' is not used much anymore, since it tends to have a negative meaning (the word 'simian' refers to a monkey or ape). The crease is usually just referred to as a single palmar crease.
Considerations
Distinct lines that form creases appear on the palms of the hands and soles of the feet. The palm usually has 3 of these creases. But sometimes, the creases join together to form just one.
Palmar creases develop while a baby is growing in the womb, usually by the 12th week of gestation .
Gestation is the period of time between conception and birth. During this time, the baby grows and develops inside the mother's womb. Gestational ag...

What to Expect at Your Office Visit
An infant with a single palmar crease may have other symptoms and signs that, when taken together, define a specific syndrome or condition. Diagnosis of that condition is based on a family history, medical history, and complete physical exam.
Your health care provider may ask questions such as:
- Is there a family history of Down syndrome or other disorder associated with a single palmar crease?
- Does anyone else in the family have a single palmar crease without other symptoms?
- Did the mother use alcohol while pregnant?
- What other symptoms are present?
Based on the answers to these questions, the medical history, and the results of the physical exam, further testing may be necessary.

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 (known in palmistry as the 'heart line' and the 'head line'). It is often found in Down Syndrome,[1] but is not necessarily an indication that a person with single transverse palmar crease has the condition. It is only found in 1.5% of the world population in at least one hand.[2]
Because it resembles the usual condition of non-human simians, it is also known as a simian crease or simian line, although these terms have widely fallen out of favor due to their pejorative connotation.[3]
Medical significance[edit]
Males are twice as likely as females to have this characteristic, and it tends to run in families. In its non-symptomatic form, it is more common among Asians and Native Americans than among other populations, and in some families there is a tendency to inherit the condition unilaterally; that is, on one hand only.[citation needed]
The presence of a single transverse palmar crease can be, but is not always, a symptom associated with abnormal medical conditions, such as fetal alcohol syndrome, or with genetic chromosomal abnormalities, including Down syndrome (chromosome 21), cri du chat syndrome (chromosome 5), Klinefelter syndrome, Wolf-Hirschhorn Syndrome, Noonan syndrome (chromosome 12), Patau syndrome (chromosome 13), IDIC 15/Dup15q (chromosome 15), Edward's syndrome (chromosome 18), and Aarskog-Scott syndrome (X-linked recessive), or autosomal recessive disorder, such as Leukocyte adhesion deficiency-2 (LAD2).[4] A unilateral single palmar crease was also reported in a case of chromosome 9 mutation causing Nevoid basal cell carcinoma syndrome and Robinow syndrome.[5] It is also sometimes found on the hand of the affected side of patients with Poland syndrome, and craniosynostosis.
