Medical workers in East China's Jiangsu Province discovered one rare case of type P blood, which is considered even rarer than "dinosaur blood" or "panda blood" subtypes.
The discovery added a new case of rare blood types being recorded in history. According to the People's Daily, rhesus negative blood type, commonly known as "panda blood," accounts for about 0.4% in the Chinese population, and para-bombay phenotype, known as "dinosaur blood," accounts for about one in 10,000 to one in 100,000, while the frequency of P blood type is lower than one in a million.
The extremely rare blood type has been discovered in Jiangsu. According to Cao Guoping, a doctor from Taixing People's Hospital, the results of gene sequencing in this case are not consistent with all reported P group gene mutations.
Currently, there are only nine recorded cases of p blood type in China. Data showed that there are five regular phenotypes in the P blood group system - P1, P2, P1k, P2k, and p.
In this case, it was confirmed that a nucleotide sequence that has to date not been found elsewhere in the world within the P blood group, a fact confirmed after Cao sent the sequencing results to the human gene bank in December 2023.
