Five polymorphic CA-dinucleotide repeats, identified in cosmids from t
he short arm of the human X chromosome, have been characterized and lo
calized to Xp21.1 (DXS572), Xp11.4 (DXS556, DXS574), and Xp11.22-p11.2
3 (DXS722, DXS573). Genetic mapping with respect to five reference mar
kers that include the gene for CGD (CYBB in Xp21.1), complemented by p
hysical mapping information, has indicated the order tel - DXS572 - CY
BB - DXS1110 - DXS556 - DXS574 DXS7 - DXS426 - DXS722 - DXS573 - DXS25
