Gs129

Gs129
Magnitude	2
Repute
Summary	Unable to classify the ABO blood type
Criteria	Gs129/criteria

Most people have SNPs which make it fairly easy to determine their ABO blood group. This text shows when Promethease was unable to make a more specific determination. Most people who see this are A+, however it has now been observed for O+, a BO-, and AB+. The full list of relevant snps is in your report under "Medical Conditions/ABO blood group".

This genoset was introduced before the 23andMe v3. It may now be possible to further improve this genoset into more specific ones.

Most respondents self reported as A+, however one O+ reported these genotypes:

• rs8176719(D;I)
• rs8176747(C;C)
• rs8176746(G;G)
• rs8176743(C;C)
• rs7853989(C;G)
• rs41302905(C;T)

One B- has now also reported "My blood type is B, believed B–, unless I am a weak positive. My mother is O, so I am BO"

• rs8176719(I;I)
• rs8176747(G;G)
• rs8176746(G;T)
• rs8176743(C;T)
• rs7853989(C;C)
• rs41302905(T;T)

someone with B+ reports

• rs8176719(I;I)
• rs8176747 GG
• rs8176746 GT
• rs8176743 CT (23andMe)
• rs7853989 CC
• rs41302905 CT

someone with B- reports "My blood type is B– My father is O, so I am BO"

• rs8176719(II)
• rs8176747 GG
• rs8176746 GT
• rs8176743 CT
• rs7853989 CC
• rs41302905 CT
