Mapping of the Tuple1 Gene to Mouse Chromosome 16A-B1

The human TUPLE1 gene encodes a putative transcriptional regulator and maps to chromosome 22, and therefore may play a role in Di-George syndrome (DGS), relo-cardio-facial syndrome (VCFS), or a related pathology. The murine TUPLE1 gene has also been cloned and shows strong sequence similarity to TUPLE1. Comparative mapping is useful in the study of chromosome evolution and is sometimes able to indicate possible mouse mutations that are potential models of human genetic disorders. As TIPLE1 is a candidate gene for the haploinsufficient phenotype in DGS, we mapped TUPLE1 to mouse chromosome 16A-B1. 6 refs., 1 fig.
