    Abstract

    We report here the identification of two distinct human cDNAs, called VNN1 and VNN2, related to the recently described mouse Vanin-1 molecule involved in lymphocyte migration (M. Aurrand-Lions et al., 1996, Immunity 5: 391-405). Tissue distribution of the expression of these two human Vanin-like genes is differential. Since Vanin-1 shares significant homologies with human biotinidase (BTD), we describe here a new family of related genes including at least four members: mouse Vanin-1, VNN1, VNN2, and BTD. We have mapped the murine locus encompassing the Vanin-1 gene on mouse chromosome 10 in position A2B1. The two human Vanin-like genes are closely linked, since they were found on the same YAC clone and colocalized on human chromosome 6q23-q24 known to contain several genetic alterations linked to the progression of metastatic human cancers.
