Abstract
Fetal pleural effusion has been reported to be associated with chromosomal abnormalities, genetic syndromes, obstructive uropathy, lymphatic vessel abnormalities such as Noonan syndrome, RASopathy and congenital lymphatic anomalies, thoracic cavity defects, Rh or ABO incompatibility, non-immune hydrops fetalis, infections, congenital cardiac anomalies, metabolic diseases and hematologic diseases such as α-thalassemia. This review provides a comprehensive view of specific and non-specific chromosome aberrations associated with fetal pleural effusion which is useful for genetic counseling and fetal therapy at prenatal diagnosis of fetal pleural effusion.

[PMID: 22641563 DOI: 10.1002/bdra.23019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2012] [Revised: 03/14/2012] [Accepted: 03/15/2012] [Indexed: 11/10/2022]
Abstract
BACKGROUND Wolf-Hirschhorn syndrome (WHS) is caused by a deletion involving the 4p16.3 region. Approximately 70% of WHS patients have a de novo isolated deletion and 22% involve unbalanced translocations. However, WHS with unbalanced rearrangements involving the short arm of an acrocentric chromosome are infrequently reported. METHODS Cytogenetic and molecular analyses by using standard G-banding, argyrophilic nucleolar organiser region (Ag-NOR) staining, fluorescence in situ hybridization, and single nucleotide polymorphism array for copy number detection were performed in three patients with WHS phenotype from two Chinese families. RESULTS A heterozygous 2,767,380-bp terminal 4p deletion was detected in patients 1 and 2 and a heterozygous 5,047,291-bp terminal 4p deletion was detected in patient3. Clinical comparisons among our patients and previously reported cases have been reviewed. CONCLUSION Two terminal 4p deletions were identified in three WHS patients with a satellited 4p and an attempt was made to refine the genotypic-phenotypic correlations of the deleted regions.

Abstract
We report on an intellectually disabled girl with a de novo satellited chromosome 10 (10qs) and performed a review of the literature of the non-acrocentric satellited chromosomes (NASC). Satellites and stalks normally occur on the short arms of acrocentric chromosomes; however, the literature cites several reports of satellited non-acrocentric chromosomes, which presumably result from a translocation with an acrocentric chromosome. This is, to our knowledge, the third report of a 10qs chromosome. The phenotype observed in the proband prompted a search for a structural rearrangement of chromosome 10q. By microsatellite analysis we observed a 4 Mb deletion on the long arm of chromosome 10, approximately 145 kb from the telomere. FISH and array CGH analyses revealed a complex rearrangement involving in range from the centromere to the telomere: A 9.64 Mb 10q26.11-q26.2 duplication, a 1.3 Mb region with no copy number change, followed by a 5.62 Mb 10q26.2-q26.3 deletion and a translocation of satellite material. The homology between the repeat sequences at 10q subtelomere region and the sequences on the acrocentric short arms may explain the origin of the rearrangement and it is likely that the submicroscopic microdeletion and microduplication are responsible for the abnormal phenotype in our patient. The patient presented here, with a 15-year follow-up, manifests a distinct phenotype different from the 10q26 pure distal monosomy and trisomy syndromes.

Abstract
We report on a case of satellited 15q with subtelomeric deletion in a girl with delayed development and severe growth retardation. The patient also has a triangular face, downturned angles of the mouth, micrognathia, and minor limb malformations including mild talipes equinovarus, genu recurvatum, and increased dorsiflexion of both limbs. Cytogenetic analysis using standard GTG banding showed a female karyotype with a satellited-like structure at the distal long arm of one chromosome 15. Silver staining of the nucleolar organizing region (AgNOR) confirmed the presence of a satellite DNA translocation at the lesion. Analysis using fluorescent in situ hybridization (FISH) detected a subtelomeric deletion of the terminal 15q. Additional molecular analysis using microsatellite markers along the long arm of chromosome 15 defined a maximally deleted region at approximately 4.7 Mb. Haploinsufficiency of the IGF1R gene expression is thought to be the cause of growth delay in all 15q terminal deletion including our patient.

Abstract
OBJECTIVE To present a case of premature ovarian failure (POF) and a complex chromosomal rearrangement involving band Xq21. DESIGN Case report. SETTING Department of cytogenetics, general analysis laboratory. PATIENT(S) A woman with POF and a complex translocation involving chromosomes X and 2 and a nucleolus organizer region (NOR) structure inserted in the critical region Xq21. INTERVENTION(S) Chromosomal analysis, NOR banding, hysteroscopy. MAIN OUTCOME MEASURE(S) Fluorescence in situ hybridization, comparative genome hybridization, human androgen receptor gene technique. RESULT(S) Four mechanisms may explain a causal relationship between the phenotype of the patient and her chromosome constitution. The presence of a NOR structure at the breakpoint of chromosome X suggests a complex reorganization and is of interest per se. CONCLUSION(S) Cytogenetic analysis is essential in women with unexplained POF and may provide valuable information on the chromosome location of critical regions implicated in ovarian function. However, in very complex reorganizations such as that described herein, classical cytogenetic techniques must be combined with molecular techniques to achieve a more complete characterization of the anomaly.

Abstract
We present the case of a pregnant woman with low free beta-HCG in maternal serum Down syndrome screening that led to prenatal diagnosis of a fetus with 46,XY,der(4)t(4;11)(p14; q25). This chromosomal aneuploidy resulted from unbalanced segregation of a paternal balanced translocation, t(4;11)(p14;q25). Prenatal ultrasound revealed intrauterine growth restriction, cleft lip and palate, a thick nuchal fold, a single umbilical artery, and pyelectasis. Array-based comparative genomic hybridization and short tandem repeat markers further located the exact breakpoint of translocation. The woman had her pregnancy terminated at 23 weeks of gestational age. The proband had general appearance of Wolf-Hirschhorn syndrome and some unique findings, including single umbilical artery, severe immunoglobulin deficiency, scalp defect, and underlying bony defect. Our case underscores the importance of fetal karyotyping when low maternal serum free beta-HCG is found. It also adds information on the fetal presentations of monosomy 4p14-->pter and trisomy 11q25-->qter.

Abstract
Nucleolus organizer regions (NORs) are present on the satellite stalks located on the short arms of the acrocentric chromosomes. NORs present on non-acrocentric chromosomes (ectopic NORs) are rare and were reported in both phenotypically normal and abnormal individuals. We describe a patient, ascertained prenatally, with an ectopic NOR on 1p and a ring 21 chromosomes. Amniocentesis was performed at 27-weeks gestation on a 19-year-old woman after identification of intrauterine growth retardation (IUGR) by ultrasound. Cytogenetic analysis of amniocytes from the fetus showed a mos 46,XX,1ps,r(21) (p11.2q22.3)[44]/45,XX,1ps,-21[6] karyotype. Parental karyotypes were normal, indicating a de novo origin for these rearrangements in the fetus. Molecular cytogenetic characterization of the 1ps showed no loss of euchromatin and retention of the telomeric repeats. Characterization of the r(21) using array comparative genomic hybridization (CGH) identified that the deletion was approximately 5 Mb encompassing most of chromosome band 21q22.3. The ectopic NOR (1ps) was most likely derived from the acentric 21p fragment generated by the chromosome breakage event that lead to formation of the r(21) chromosome. This represents a novel mechanism for the origin of ectopic NORs. In addition, this study illustrates the importance of FISH analysis with telomeric and subtelomeric probes for characterization of chromosomes with ectopic NORs.

Abstract
BACKGROUND: Wolf-Hirschhorn syndrome is caused by distal deletion of the short arm of chromosome 4 (4p-). We report a case in which intrauterine growth restriction, hypospadias and foot deformity were detected by prenatal ultrasound examination at 29 weeks of gestation. CASE PRESENTATION: A 31-year-old gravida 2 partus 1 woman was referred at 29 weeks' gestation with suspicion of intrauterine growth restriction. Sonographic examination revealed deformity of the right lower limb and undescended testes with an irregular distal penis. A cordocentesis was performed and chromosome analysis revealed a 46,XY,del(4)(p14) karyotype. CONCLUSION: The prenatal detection of intrauterine growth restriction, hypospadias and foot deformity should lead doctors to suspect the presence of Wolf-Hirschhorn syndrome.

Abstract
OBJECTIVES Although there have been occasional reports of prenatal diagnosis of this syndrome, most cases are diagnosed postnatally. The objective was to evaluate the presence of brain abnormalities in the prenatal diagnosis of Wolf-Hirschhorn syndrome. METHODS Prenatal ultrasound and MRI examination of the fetal brain were performed in a case of Wolf-Hirschhorn syndrome. A comprehensive review of Wolf-Hirschhorn syndrome reported between 1960 and 2000 in the literature was carried out. RESULTS The late diagnosis of a growth-retarded fetus with normal amniotic fluid volume, normal Doppler and negative infection screen calls for a detailed examination of the fetal brain and heart. Multifocal white matter lesions and periventricular cystic changes, which are often attributed to perinatal distress, are possible prenatal features causing suspicion of 4p- syndrome in an IUGR fetus. CONCLUSION Subtle abnormalities on ultrasound may suggest a chromosomal problem. Standard cytogenetics cannot always demonstrate a microdeletion. High-resolution banding and molecular analysis can help to confirm the diagnosis.
