Hypothesis
The study aimed to characterize the molecular mechanism underlying a novel AEL allele associated with an intron splice site mutation.
Conclusion
A novel AEL allele was identified in a Chinese male blood donor, characterized by the c.28 + 5G>A variant, which alters normal splicing and leads to a truncated glycosyltransferase.
Supporting Evidence
- The proband exhibited an atypical agglutination pattern.
- PacBio sequencing revealed a novel ABO*A2.01-like allele with a c.28 + 5G>A mutation.
- Minigene analysis indicated that the mutation disrupted normal splicing.
Takeaway
Scientists found a new type of blood group that changes how blood cells behave, which can affect blood transfusions.
Methodology
PacBio sequencing and minigene splicing assays were used to analyze the ABO gene and its mutations.
Participant Demographics
A 53-year-old healthy male blood donor.
