The human myoglobin gene: a third dispersed globin locus in the human genome.

RESUMO

Human myoglobin is specified by a single gene. Unique sequence DNA probes were isolated from the cloned gene and used to test for the presence of the human myoglobin gene in a series of human rodent somatic cell hybrids containing various complements of human chromosomes. The myoglobin gene cosegregated with human chromosome 22. Somatic cell hybrids containing translocation chromosomes carrying part of chromosome 22 were used to locate the myoglobin gene to the region 22q11----22q13. The myoglobin gene is therefore not linked to the alpha-globin gene cluster on chromosome 16 or the beta-globin cluster on chromosome 11, and represents a third dispersed globin locus in the human genome.
