PHENOTYPE: This locus controls transcobalamin-2 electrophoretic variation. The s allele determines a slow band in serum from A/J, C57BL/6, BALB/c and C3H/He; the f allele determines faster form in NZB, ST/b and CPB-WV. Heterozygotes have both forms. Sequencing reveals a Gly to Glu substitution in NZB compared to BALB/c, DBA/2 and C57BL/6 (Genbank AF090686). [provided by MGI curators]
