Abstract
A c[complementary]DNA for the pro.alpha.2 chain of human type I collagen was recently cloned and amplified. This specific probe was used to identify the human chromosome carrying the pro.alpha.2(I) collagen gene. The DNA from 17 independent human/hamster and human/mouse somatic cell hybrids was digested by Eco RI and the restriction pattern analyzed in Southern blot experiments, using the 32P-labeled cDNA as a hybridization probe. The gene coding for the pro.alpha.2 collagen subunit could be unambiguously assigned to human chromosome 7. All the other chromosomes, including chromosome 17, were excluded.
