Medical professionals in China’s Jiangsu province have uncovered the genetic sequence behind a rare case of type P blood group – even rarer than the subtypes akin to “dinosaur blood” or “panda blood.”

According to People’s Daily, the rhesus-negative blood type sometimes called “panda blood” in China, includes roughly 0.4 per cent of the Chinese inhabitants. In comparability, the para-bombay phenotype, generally known as “dinosaur blood” accounts for about one in 10,000 to at least one in 100,000.

The Global Times reported that the P blood type happens much more sometimes, with a prevalence decrease than one in 1,000,000.

Now, scientists have recognized the DNA sequence – nucleotide molecules – behind the rare blood type P in an individual with the blood group subtype, Modern Express Post reported on Saturday.

Nucleotides are small molecules that make up DNA and RNA, which carry genetic data.

After additional genetic testing, it was confirmed that the newly found gene sequence had by no means been discovered earlier than.

For individuals with this rare P blood type, early detection will help put together higher for blood transfusions.

This is very so on the time of being pregnant as such people can solely obtain blood of the identical variety and incorrect transfusion could result in miscarriages and stillbirths.

The newest discovery of the DNA sequence behind this rare blood group happened throughout common exams carried out final 12 months at a hospital in Taizhou, Jiangsu province, South China Morning Post reported, citing a Chinese medical journal.

Cao Guoping, a health care provider at Taixing People’s Hospital instructed the Global Times that the gene sequencing outcomes on this specific case didn’t align with the recognized mutations reported for the P group.

Currently, there have been solely 9 documented circumstances of the p blood type in China. According to obtainable knowledge, the P blood group system includes 5 common phenotypes: p1, p2, p1k, p2k, and p.

“After passing the examination by experts from the National Center for Biotechnology Information of the United States, the gene of this cis-AB blood group is now officially included and published in the ‘GenBank’ database that has shared it to the world as a new gene,” Zhang Qian, deputy director of the Laboratory of Baoji Central Blood Station, was quoted as saying by Huashang Daily.

“In the case of female individuals with this blood type, the presence of ‘anti-Tja’ antibodies attacking the placenta directly can lead to recurrent miscarriages and stillbirths,” Dr Cao stated, referring to the naturally occurring antibody towards the P blood group, based on SCMP.
