Chromosomal assignment of seven human genomic DNA sequences associated with restriction fragment length polymorphisms

Seven phage clones containing human sequences were picked at random from a human genomic library cloned in Charon 4A. The clones are devoid of repetitive sequences and can be used to recognize restriction fragment length polymorphisms (Feder et al. 1985). The chromosomal locations of the sequences defined by the seven clones have been determined by Southern blotting and DNA hybridization to DNA from human-mouse somatic cell hybrids. The chromosomal assignment of these sequences should increase their value as genetic markers in family studies.
