Establishing a relationship between clinical features and one specific type of chromosome abnormality

We read the article by Thillainathan[1]and colleagues published in this Journal.The authors provided descriptive analysis of children in Sri Lankan who underwent cytogenetic analysis for suspected chromosomal disorders.They compared their results with that in Caucasian and other Asian populations.This is an important document in that the authors added their data of Sri Lanka to the international pool of these types of surveys.[2,3]However,further analyses may benefit the impact of the current study.
