Regional localization of the human EGF-like growth factor CRIPTO gene (TDGF-1) to chromosome 3p21

Hum Genet. 1995 Feb;95(2):229-30. doi: 10.1007/BF00209409.

Abstract

The CRIPTO gene encodes a novel human growth factor structurally related to epidermal growth factor. We localized the CRIPTO gene to chromosome 3p21 by fluorescence in situ hybridization with a cosmid clone containing 40 kb of the CRIPTO genomic region (TDGF-1). To suppress hybridization to CRIPTO-related sequences, present in multiple copies in the human genome, hybridization was carried out in the presence of unlabeled CRIPTO cDNA in excess over the probe. Our finding confirms the provisional mapping of the CRIPTO gene to chromosome 3, and assigns it precisely to a chromosomal region involved in several rearrangements occurring in malignancy.
