Deletion of a 702bp HindIII fragment within the c(3)G coding region. This is expected to remove amino acid residues 340-352 (in-frame).
The exchange on the X chromosome seen in c(3)G68 females carrying c(3)GtX204 has an altered distribution, known as polar exchange distribution.
c(3)GtX204 partially rescues c(3)G68
Partially restores exchange on the X chromosome in c(3)G68 females.
