Responsible for familial Down Syndrome:
Robertsonian Translocation
This occurs when the long arms of two acrocentric chromosomes will fuse at their centromere
and here the acrocentric chromosomes are 13, 14, 15, 21 and 22
Responsible for Burkitt's Lymphoma:
Reciprocal Translocation
The reciprocal chromosome translocation, t(8;14) is responsible and it involves the heavy chain
locus on chromosome 14 and the c-myc oncogene on chromosome 8.
Dicentric bridges are common in heterozygotes:
Paracentric Inversion
Dicentric chromosome with two centromeres will be seen simultaneously dragged to opposite
poles at anaphase, this will form the anaphase bridge and this will not be incorporated into either
progeny cell.
During meiosis, produces an acentric fragment (one without a centromere) due to crossing-over
within the inversion loop of a heterozygous paracentric inversion which is found to be
connecting the homologous centromeres in a dicentric bridge.
Responsible for Turner Syndrome:
Reciprocal Translocation
In turner syndrome, the female will be missing the X chromosome partially or entirely, thus will
have a variety of complications (developmental delay, infertility, cardiac abnormalities etc)
