China Finds Rare Case of Blood Type P Lifestyle – 3 hours ago


Jakarta, CNBC Indonesia – Doctors in China have just discovered a new nucleotide sequence for the rare blood type P, a subtype of blood type P.

Launching from South China Morning Post (SCMP), this previously unknown nucleotide sequence was discovered last Saturday (6/1/2024). This sample was obtained during a routine blood test at a hospital in Taizhou, Jiangsu Province.

For your information, nucleotides are one of the many small molecules that make up DNA and RNA, namely nucleic acids that carry genetic information.


According to reports Modern Express Post quoted SCMP, the number of people with blood type P in China is very rare, namely only about “12 dozen cases”. In fact, the report states that the frequency is lower than one in a million.

Staff at Taixing People's Hospital have submitted the genetic sequence to the GenBank sequence database. GenBank is an open access collection managed by the National Center for Biotechnology Information in the United States (US). Meanwhile, this sequence was then given the serial number OR900206 in the human gene database.

The transfusion specialist who detected the rare sample, Cao Guoping, said that this finding is very important for individuals who have rare blood types. Because, early detection can help prepare oneself for blood transfusions and potential crises related to blood needs.

For example, blood type P can only receive transfusions of the same type, especially during pregnancy.

“In the case of women with this blood type, the presence of 'anti-Tja' antibodies that attack the placenta directly can cause recurrent miscarriages and stillbirths,” said Gouping, referring to natural antibodies against blood type P.

What is Blood Type P?

According to the SCMP report, blood type P was first discovered in 1927. Blood samples can be categorized into five subtypes, depending on the antigens on the surface of the red blood cells.

Blood group subtypes P1 and P2 are more often found in testing blood group P. Meanwhile, subtypes P1k, P2k, and P are very rare and rarely found.

In testing, blood type P is more often easily missed because it cannot be picked up by the reagents available for ABO and Rh blood types.

Most of the world's population belongs to the ABO and Rh blood group systems. However, there are other blood types that are less common, such as the Hh/Bombay antigen system and the P blood group.

The Rh null blood type, also known as the “gold” blood type, does not contain the Rh antigen in its red blood cells.

In China, Rh-negative blood also known as “panda blood” is found in about 0.4 percent of the population.

Then, around 100 people in China were recorded as having the Hh/Bombay blood type.
