Comparative gene mapping: murine lambda light chain genes are located in region cen→B5 of mouse chromosome 16 not homolous to human chromosome 21

Abstract
We have mapped the genes for murine immunoglobulin lambda light chains to the region of chromosome 16 proximal to band B5 by hybridizing a cDNA probe for X light chains to the DNA of a series of hybrid clones made between mouse fibroblasts carrying Searle’s translocation, T(X;16)16H, and Chinese hamster cells. Based on homology, we predict that the human Igl genes (IGL) will map to the proximal two-thirds of HSA 22.
