Pallister Killian Syndrome

“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.
