Eh. Mcconkey et al., ASSIGNMENT OF THE GENE FOR BETA-CASEIN (CSN2) TO 4Q13-]Q21 IN HUMANS AND 3P13-]P12 IN CHIMPANZEES, Cytogenetics and cell genetics, 72(1), 1996, pp. 60-62
The human beta-casein gene (CSN2) has been mapped by fluorescence in s
itu hybridization to human chromosome 4q13-->q21 and to the homologous
chimpanzee chromosome at 3p13-->p12. This confirms the presence of a
pericentric inversion that distinguishes the two species, as first obs
erved by chromosomal banding studies.
