Is there a cure for Pallister-Killian Syndrome?
Treatment. Currently, there is no cure for Pallister-Killian syndrome. Treatments offered to children with the condition can help manage each child’s specific symptoms and developmental needs.
Is Pallister-Killian Syndrome inherited?
Pallister-Killian mosaic syndrome is not inherited. The chromosomal change responsible for the disorder typically occurs as a random event during the formation of reproductive cells (eggs or sperm) in a parent of the affected individual, usually the mother.
When is Pallister-Killian Syndrome diagnosed?
Pallister-Killian mosaic syndrome can be diagnosed before birth (prenatally) by removing a small amount of fluid that is in the womb during pregnancy (amniocentesis) or by removing a small number of cells from outside the sac where the fetus develops (chorionic villous sampling).
Who discovered Pallister Killian?
Pallister-Killian syndrome (PKS) was first described an adult phenotype by Pallister in 1977 and independently a childhood phenotype by Killian and Teschler-Nicola in 1981 [1, 2]. In both instances, cytogenetic examinations of blood cells did not reveal any abnormality.

What are the characteristics of Pallister Killian syndrome?
▼ Description. Pallister-Killian syndrome is a dysmorphic condition involving most organ systems, but also characterized by a tissue-limited mosaicism; most fibroblasts have 47 chromosomes with an extra small metacentric chromosome, whereas the karyotype of lymphocytes is normal.
What is the extra metacentric chromosome in Pallister Killian syndrome?
The extra metacentric chromosome is an isochromosome for part of the short arm of chromosome 12: i (12) (p10) ( Peltomaki et al., 1987; Warburton et al., 1987 ). Schinzel (1991) reviewed the clinical and cytogenetic features of the Pallister-Killian syndrome.
What is the other name for Pallister-Killian syndrome?
Pallister-Killian syndrome is also known as isochromosome 12p syndrome, tetrasomy 12p mosaicism, Pallister-Killian mosaic syndrome and PKS. Pallister-Killian syndrome is a chromosomal disorder caused by having an extra chromosome.
How is Pallister-Killian syndrome (PK) diagnosed?
Soukup and Neidich (1990) made the diagnosis of Pallister-Killian syndrome on routine amniocentesis. In the aborted fetus, various degrees of mosaicism were found in 4 tissues. Thakur et al. (2019) reviewed the prenatal findings associated with Pallister-Killian syndrome.
