Gene: Ptprc  Location: Chr1:137990599-138103446 bp, - strand  Genetic Position: Chr1, 60.73 cM
Strain of Origin:  Not Applicable
Allele Type:    Not Applicable
Mutation:    Nucleotide substitutions
Mutation detailsPtprca is found in strains SJL/J, STS/A, and DA. Ptprcb is found in strains C57BL/6, C3H/An, DBA/2, AKR, and many others (J:13367, J:12054, J:12077, J:8603). Twelve nucleotide differences between the a and b alleles have been identified. These base substitutions correspond to five amino-acid changes within the extracellular domain of the encoded protein. These amino-acid differences are clustered in a region that also contains the greatest divergence between mouse and rat sequences (J:22485).

Note that the allele designations originally described were reversed in 1987 (J:8603); all publications prior to 1987 show SJL/J, STS/A, and DA as having the b allele and the C57BL/6J group as having the a allele (J:22341). (J:8080, J:12548, J:22485)
