Patau syndrome is a syndrome caused by a chromosomal abnormality, in which some or all of the cells of the body contain extra genetic material from chromosome 13. This can occur either because each cell contains a full extra copy of chromosome 13 (a disorder known as trisomy 13 or trisomy D), or because each cell contains an extra partial copy of the chromosome (i.e., Robertsonian translocation) or because of mosaic Patau syndrome.


Balanced Trans location Support Group - This support group is for men & women struggling with a Balanced Translocation (BT) or an Inversion, both of which are chromosomal abnormalities that often lead to battles with infertility, recurrent miscarriage & pregnancy loss.

Scientists decipher the molecular basis of an as yet incurable leukemia in children - Although intensive research over the least decade has led to significant improvement of the survival rates of children suffering from ALL, a subset of patients still remains resistant to treatment. One such example is a very aggressive and incurable subtype associated with a t(17;19) chromosomal translocation, which occurs due to breakage and aberrant fusion of genetic material in the tumour cells…
