When a mother to be in Nanjing was undergoing antenatal examination in the hospital, the hospital found that her blood type was abnormal. Unexpectedly, there was a very rare blood type in the world, belonging to a subtype of a, so I hope that this mother must be healthy in the future, or it will be very difficult to find a matching blood type in case of accidental blood transfusion!
Recently, a research group led by researcher Chen Qing of blood transfusion Research Office of Jiangsu blood center found a rare blood group for the first time in the world, which has been included and published by the international gene bank.

When a mother to be in Nanjing was undergoing antenatal examination in the hospital, the blood type of her mother to be was found to be abnormal and could not be determined. In order to accurately detect the blood type of the mother to be, and in order to prepare blood during production, the hospital sent the samples to the research room of Jiangsu Blood Center for further detection.

Through serological blood group reexamination and further gene detection, the staff of blood transfusion Research Office of Jiangsu blood center found that there was a new mutation in the ABO gene of the mother to be. The new base mutation led to the amino acid change, resulting in the weakening of the expression of a antigen of the mother to be, thus showing abnormal phenomena. In a popular sense, the blood type of the mother to be is type A, but due to the mutation of the ABO allele, it belongs to a subtype of type A.
The existence of ABO blood group subtype has caused many misunderstandings. After his son was scalded, Lin, a Guangdong resident, found that his son's blood type was type B, but both he and his wife were type o. According to the law of blood type heredity, Mr. Lin can't have a son with type B blood. Later, after repeated reexamination, it was found that Mr. Lin's blood type was subtype B, which was very rare and misdiagnosed as type o.
