Overview

Blood types A, B and AB/C in cats

This genetic analysis examines four CMAH variants: c.179G>T, c.268T>A, c.1322delT and c.364C>T. Together, these markers help determine the genetic background of the feline AB blood group system. Cats can have blood type A, B or AB; in genetic contexts, AB is also often referred to as C.

The CMAH gene is involved in the formation of sialic acid on red blood cells. Differences in this gene influence which blood group antigens are present, making the result valuable for transfusion planning, breeding selection and assessment of blood group compatibility.

Practical value of this test

Helps determine whether a cat genetically fits blood type A, B or AB/C.
Supports targeted breeding selection, especially in lines where blood type B or AB/C occurs.
Helps assess the risk of neonatal isoerythrolysis when parent animals have different blood group backgrounds.
Provides useful information for transfusion planning and blood group compatibility.

The result is interpreted from the combined pattern of all tested CMAH markers. Because rare or not yet included variants can exist, a complete laboratory interpretation of the marker combination remains important.

Included subanalyses

This analysis includes the following subanalyses:

Blood group b1 / CMAH c.268T>A - Cat
Blood group b2 / CMAH c.179G>T - Cat
Blood group b3 / CMAH c.1322delT - Cat
Blood group c / AB / CMAH c.364C>T - Cat

Below, for each tested locus, you will find the possible allele combinations that may be reported within this analysis, together with a brief explanation of their genetic meaning. The interpretation of possible interactions between different loci is included in the report, but is not shown here in full because that would lead to too many combinations on this page. The final expression may also depend on other genes and their interaction.

b1

Genotype / allele combination: Variant not detected

This cat has no copy of the tested b1 allele. Interpret this together with the other CMAH markers for the final genetic blood type.

Genotype / allele combination: One copy detected

This cat carries one copy of the b1 allele. This can be relevant for combined blood type interpretation and breeding choices.

Genotype / allele combination: Two copies detected

This cat has two copies of the b1 allele. This result strongly contributes to the combined CMAH interpretation of blood type B or AB/C, depending on the allele and the other markers.

b2

Genotype / allele combination: Variant not detected

This cat has no copy of the tested b2 allele. Interpret this together with the other CMAH markers for the final genetic blood type.

Genotype / allele combination: One copy detected

This cat carries one copy of the b2 allele. This can be relevant for combined blood type interpretation and breeding choices.

Genotype / allele combination: Two copies detected

This cat has two copies of the b2 allele. This result strongly contributes to the combined CMAH interpretation of blood type B or AB/C, depending on the allele and the other markers.

b3

Genotype / allele combination: Variant not detected

This cat has no copy of the tested b3 allele. Interpret this together with the other CMAH markers for the final genetic blood type.

Genotype / allele combination: One copy detected

This cat carries one copy of the b3 allele. This can be relevant for combined blood type interpretation and breeding choices.

Genotype / allele combination: Two copies detected

This cat has two copies of the b3 allele. This result strongly contributes to the combined CMAH interpretation of blood type B or AB/C, depending on the allele and the other markers.

c / AB

Genotype / allele combination: Variant not detected

This cat has no copy of the tested c / AB allele. Interpret this together with the other CMAH markers for the final genetic blood type.

Genotype / allele combination: One copy detected

This cat carries one copy of the c / AB allele. This can be relevant for combined blood type interpretation and breeding choices.

Genotype / allele combination: Two copies detected

This cat has two copies of the c / AB allele. This result strongly contributes to the combined CMAH interpretation of blood type B or AB/C, depending on the allele and the other markers.
