Question
I need help with putting the appropriate symbols for these chromosome rearrangements. The questions are:
A. A deletion in region 2, band 5 in the long arm of chromosome 4
B. Paracentric inversion(with two breaks in the same arm) in the long arm of chromosome 6, region 1, with break points in bands 2 and 6
C. Translocation of the long arm of chromosome 14 with the retention of the chromosome 14 centromere. Assume a break in the short arm of chromosome 14 at region 1 band 1 and the loss of the entire short arm of 21
The chromosome resulting from this translocation is properly referred to as a _____ chromosome?
D. A pericentric inversion in chromosome 2 with break points in region 1, band 4 of the short arm and region 2, band 3 of the long arm
I tried A and my answer for that is del(4)(q25). I don't know where to start for B,C, and D.
Explanation / Answer
A. Del(4)(q5.2)
B. In(6)(q2.1,6.1)
C. T(14p.1.1 : 21.1)
D. In(2p.3.2 : q3.2)
