A cDNA probe corresponding to mRNA encoding human somatomedin-C/insulin-like growth factor I (IGF-I) was used for the chromosomal assignment of the IGF-I gene. Southern-blot hybridization analysis of DNA from human-Chinese hamster somatic cell hybrids showed that the IGF-I gene is located on chromosome 12. Comparison of the chromosomal assignments of the IGF-I gene and two other members of the insulin gene family, with three c-ras oncogenes, reveals a remarkable association of the two gene families.
