How is Pallister Killian Syndrome diagnosed?
Pallister-Killian syndrome can also be diagnosed before birth by amniocentesis or chorionic villus sampling (CVS). These tests involve removing a small amount of amniotic fluid that surrounds a baby in the womb, or a sample of chorionic villi, tissue from the placenta which has cells from the baby.

What chromosome is Isobrachial?
Iso – equal Brachus – arm An isobrachial chromosome is one in which the two arms are equal in length. Usually metacentric chromosomes (the chromosomes in which the primary constriction is in exactly the middle) are isobrachial. They are much larger than normal chromosomes around 2000 micrometres or 2mm).

What is PKS (Pallister-Killian syndrome)?
Pallister-Killian syndrome is also known as isochromosome 12p syndrome, tetrasomy 12p mosaicism, Pallister-Killian mosaic syndrome and PKS.

All cases recorded to date have been sporadic.
What is tempallister-Killian syndrome?

What is the prevalence of PKS?
Pallister-Killian syndrome (PKS) is an extremely rare genetic disorder that is present at birth. The prevalence has been estimated to be 1 in 20,000; however, it is likely that PKS is underdiagnosed due to the difficulty of making a cytogenetic diagnosis from a blood test.
What is the clinical phenotype of peripheral knee syndrome (PKS)?
The clinical phenotype of PKS is quite homogeneous for the dysmorphic pattern, but highly variable for developmental delay, congenital malformations, and survival. There is a wide range of congenital malformations that occur rarely including anal atresia/stenosis and atlanto-occipital fusion.
