Chromosomal assignment of the ovine hairless (hr) gene by fluorescence in situ hybridization.

Congenital hypotrichosis in mammalian species consists of partial or complete absence of a hair coat at birth. Affected individuals having a partial hair coat at birth may loose it subsequently.The aim of this paper was to physically map the ovine hr gene using fluorescence in situ hybridization (FISH).A preliminary study on an internet data bank (http://www.informatics.jax.org) showed that the regions of the hr gene on murine chromosome 14 and human chromosome 8 present homology with ovine chromosome 2.
