Gene: [02p12/IGKC] immunoglobulin, kappa subunit, constant region;
MOP | It is the CON region of kappa peptide that is related with the expression of the antigenic determinant referred to as Inv in early reports. Since late 1970s, the denotation Km (Kappa Marker) have been used. It is presumed that, when an analogous antigenic determinant related to the lambda peptide (another Ig light subunit) is found, this allotype should be denoted as Lm (Lambda Marker); up to the present, such an antigen has not been found." |
HIS | The data of some reports in 1970s on a possible linkage of Km/Inv allotype to Kidd isoantigen (Jk gene) was not confirmed. In 1980s, Jk gene was mapped to chromosome 18q with the aid of MGM (linkage to PRLP), as well as by the method of in situ hybridization on chromosome." |
CAG | Several sporadic and familial cases of a complete loss of kappa chain synthesis are described in literature; those are accounted for by mutations of the gene for CON peptide. The definite clinical manifestation of this IGK deficiency is not revealed, perhaps because the lacking kappa chains are substituted by other subunits (probably H-gamma ones)." |
