Prenatal profile of Pallister-Killian syndrome: Retrospective analysis of 114 pregnancies, literature review and approach to prenatal diagnosis. Am J Med Genet A 2018; 176:2575-2586. [PMID: 30289601 DOI: 10.1002/ajmg.a.40499] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2018] [Revised: 06/23/2018] [Accepted: 07/14/2018] [Indexed: 01/10/2023]
Abstract
Pallister-Killian syndrome (PKS) is a tissue limited mosaic disorder, characterized by variable degrees of neurodevelopmental delay and intellectual disability, typical craniofacial findings, skin pigmentation anomalies and multiple congenital malformations. The wide phenotypic spectrum of PKS in conjunction with the mosaic distribution of the i(12p) makes PKS an underdiagnosed disorder. Recognition of prenatal findings that should raise a suspicion of PKS is complicated by the fragmentation of data currently available in the literature and challenges in diagnosing a mosaic diagnosis on prenatal testing. Ultrasound anomalies, especially congenital diaphragmatic hernia, congenital heart defects, and rhizomelic limb shortening, have been related to PKS, but they are singularly not specific and are not present in all affected fetuses. We have combined prenatal data from 86 previously published reports and from our cohort of 114 PKS probands (retrospectively reviewed). Summarizing this data we have defined a prenatal growth profile and identified markers of perinatal outcome which collectively provide guidelines for early recognition of the distinctive prenatal profile and consideration of a diagnosis of PKS as well as for management and genetic counseling.

Abstract
OBJECTIVE To present five new cases of prenatally diagnosed Pallister-Killian syndrome (PKS) and to propose an approach for a targeted diagnosis. METHOD We retrospectively analyzed ultrasound findings and cytogenetic results in PKS. We also searched through dysmorphology databases for features occurring in PKS that could potentially be seen in prenatal ultrasound examination. RESULTS On the basis of collected data, frequent and distinctive features in fetuses with PKS were established. The most appropriate material and method of testing were proposed. Rhizomelic limb shortening, diaphragmatic hernia, thickened nuchal fold, increased prenasal thickness, polydactyly and polyhydramnios were frequent and distinctive findings in fetuses with PKS. Amniocentesis was the most frequent prenatal procedure for material collection. Percentage of aneuploid cells was higher in amniotic fluid than in cord blood. Cytomolecular tests were useful as confirmation as well as preliminary tests. Cytogenetic identification of the isochromosome was done in all cases except one. CONCLUSIONS In case of ultrasound evaluation of features frequent and distinctive for PKS in second and third trimesters of pregnancy, targeted diagnosis should be considered. Amniotic fluid instead of cord blood collection is preferable. Communication with the laboratory is important because modification of routine procedures enhances a chance for correct diagnosis. © 2017 John Wiley & Sons, Ltd.

Abstract
OBJECTIVE In multidisciplinary prenatal diagnosis centers, the search for a tetrasomy 12p mosaic is requested following the discovery of a diaphragmatic hernia in the antenatal period. Thus, the series of Pallister Killian syndromes (PKS: OMIM 601803) probably overestimate the prevalence of diaphragmatic hernia in this syndrome to the detriment of other morphological abnormalities. METHODS A multicenter retrospective study was conducted with search for assistance from members of the French society for Fetal Pathology. For each identified case, we collected all antenatal and postnatal data. Antenatal data were compared with data from the clinicopathological examination to assess the adequacy of sonographic signs of PKS. A review of the literature on antenatal morphological anomalies in case of PKS completed the study. RESULTS Ten cases were referred to us: 7 had cytogenetic confirmation and 6 had ultrasound screening. In the prenatal as well as post mortem period, the most common sign is facial dysmorphism (5 cases/6). A malformation of limbs is reported in half of the cases (3 out of 6). Ultrasound examination detected craniofacial dysmorphism in 5 cases out of 6. We found 1 case of left diaphragmatic hernia. Our results are in agreement with the malformation spectrum described in the literature. CONCLUSION Some malformation associations could evoke a SPK without classical diaphragmatic hernia.
