Prader-Willi syndrome: is there a recognizable fetal phenotype?

abstract：INTRODUCTION:Pure duplication of chromosome 18p is rare, with clinical phenotypes ranging from normal or slight abnormalities to various degrees of mental retardation. It remains difficult to establish a clear genotype-phenotype correlation. METHODS:Chromosomal karyotyping analysis was performed on cultured amniotic f...
