Abstract
BACKGROUND Complete cryptophthalmos, congenital aphakia, and corneal vascularization are relatively uncommon congenital eye malformations during the fetal period. Herein, we report a case of a fetus with complete cryptophthalmos, congenital aphakia, and corneal vascularization in both eyes and review previous prenatal reports of related cases. CASE PRESENTATION The patient was a 27-year-old pregnant woman, gravida 2, para 1, who was referred to our hospital for consultation at 23 weeks of gestation due to a diagnosis of fetal right renal agenesis at an external hospital. The ultrasound system of our hospital diagnosed the fetus with complete cryptophthalmos, congenital aphakia, and corneal vascularization, which was verified under the postnatal water basin test, anatomical and pathological sections. CONCLUSIONS Fetal ocular malformations are often associated with malformations of other organs, and if ultrasound findings are associated with such malformations, attention should be paid to the ocular examination to avoid missing the diagnosis.

Abstract
INTRODUCTION Fraser syndrome, named after George Fraser, is an autosomal recessive disorder showing a highly variable interfamilial phenotypic variation, with malformations ranging from minor symptoms to lethal anomalies like renal agenesis, incompatible with survival. Limb reduction defects have not been reported to be associated with it. CASE PRESENTATION A 21-year-old primigravida presented to the antenatal outpatient department with a level two targeted anomaly scan report suggestive of severe oligohydramnios with suspected renal agenesis. The cranial vault bones were compressed, and orbital globes and lenses could not be visualized. Renal agenesis was confirmed due to sleeping adrenals sign, non-visualization of the urinary bladder, and Doppler of renal arteries. A detailed examination of the fetal head in the sagittal section showed the absence of an eye globe and lens, arousing suspicion of Fraser syndrome. After pregnancy termination, a complete fetal autopsy was done to look for any additional findings. CONCLUSION Patients who have a syndromic mix of acrofacial and urogenital abnormalities with or without cryptophthalmos should be evaluated for Fraser syndrome, which can be diagnosed by clinical examination and perinatal autopsy.

Abstract
Background: It is challenging to make an accurate prenatal diagnosis for congenital anomalies of the kidney and urinary tract (CAKUT) because of its pathologic diversity. This study aims to evaluate the performance of whole-exome sequencing (WES) combined with karyotype analysis and copy number variations (CNVs) in diagnosing high-risk fetal CAKUT. Methods: We conducted a retrospective study on prenatal diagnoses of CAKUT in our hospital from January 2020 to April 2021. The research studied 24 high-risk fetuses with CAKUT who were scanned by ultrasonography at the prenatal diagnosis center of Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology. The likely pathogenic gene variants were screened for the patients and their parents by multiple approaches, including karyotype analysis, CNVs and WES, and further verified with Sanger sequencing. Results: ①We detected abnormal CNVs in 20.8% (5/24) of the fetuses but only 8.3% (2/24) fetuses had abnormal karyotypes. ②Of the 15 CAKUT fetuses, positive findings (40%) were detected by WES. Of the 9 high-risk fetuses with CAKUT (negative findings in ultrasound scan but with family history), we found abnormal variants (77.8%) through WES. Conclusion: The application of CNVs and WES showed advance in prenatal diagnosis of CAKUT and the pathogenic gene variants were detectable especially for high-risk fetuses with negative ultrasound findings on CAKUT in the preliminary study. The applied strategy could be used to improve the accuracy of prenatal diagnosis for CAKUT in the future.

Abstract
Fraser syndrome (FS) involves multiple malformations and has a 25% recurrence risk among siblings. However, these malformations are difficult to detect prenatally, hampering prenatal diagnosis. Here, we describe a fetus with FS diagnosed using ultrasonography. Ultrasonography revealed congenital high airway obstruction syndrome and renal agenesis. Syndactyly of both hands and cryptophthalmos were noted postnatally, and the diagnosis was confirmed by genetic analysis, which showed novel compound heterozygous variants of FREM2.

Abstract
INTRODUCTION Congenital anomalies of the kidney and urinary tract (CAKUT) are a group of abnormalities that affect structure of the kidneys or other structures of the urinary tract. The majority of CAKUT are asymptomatic and are diagnosed prenatally by ultrasound scanning or found incidentally in postnatal life. CAKUT varies in severity and may lead to life-threatening kidney failure and end-stage kidney disease. Renal agenesis, a severe form of CAKUT, is a congenital absence of one or both kidneys. Bilateral renal agenesis belongs to a group of prenatally lethal renal diseases and is often detected on fetal ultrasound scanning during the investigation of oligohydramnios. Approximately 40% of fetuses with bilateral renal agenesis are stillborn or die a few hours postnatally. Mutations in many renal development genes have been shown to be associated with renal agenesis. METHODS Six consanguineous Saudi Arabian families were recruited to study the molecular genetic causes of recurrent miscarriages and lost fetuses due to oligohydramnios, renal agenesis and other congenital anomalies. Whole exome sequencing was employed to underlying detect genetic defects. RESULTS Novel loss of function variants were detected in FRAS1 and FREM2. In FRAS1, a homozygous splice site variant c.9780+2T>C was found in an affected fetus, segregating form each parent. In addition, in three other families both parents were heterozygous for a frameshift variant (c.8981dupT; p.His2995Profs*3) and splice site variants (c.5217+1G>C and c.8098+2T>A), respectively. In FREM2, a homozygous nonsense variant (c.2303C>G; p.Ser768*) was found in an affected fetus, segregating from both parents. In another family, both parents carried a FREM2 heterozygous frameshift variant (c.3969delC; p.Asn1323Lysfs*5). CONCLUSION We describe consanguineous families with clinical features of antenatal oligohydramnios and bilateral renal agenesis, in whom we have identified novel pathogenic variants in FRAS1 and FREM2. These finding highlights the association between mutations in FRAS1 and FREM2 and antenatal/perinatal death.

Abstract
OBJECTIVE Fraser syndrome (FS) is a rare malformation recessive disorder. Major criteria are cryptophtalmos, syndactyly, respiratory, genital and urinary tract anomalies. Few prenatal presentations have been reported. METHOD We analyzed the prenatal and postnatal fetal phenotype in 38 cases of FS, including 25 pregnancy termination cases, 8 intra-uterine death cases and 4 cases that died after birth. RESULTS Including both prenatal and postnatal fetal phenotypic evaluation, all cases presented dysmorphic features with nose and ear dysplasia. Renal anomalies and syndactyly were present in 37/38 cases, cryptophtalmos in 36/38, airways anomalies in 30/37 and genital anomalies in 30/35 cases. Anomalies of the abdominal wall such as low set umbilicus and omphalocele were found in 31 cases. Among the 26 cases for which ultrasound data were available, detectable anomalies included oligohydramnios (22), ascites/hydrops (9), renal anomalies (20), evidence for high airways obstruction (11), ophthalmologic anomalies (4), ear dysplasia (2) and syndactyly (2). CONCLUSION This study shows that the postnatal phenotype of FS is very specific, whereas oligohydramnios hampers the prenatal recognition of the cardinal FS diagnosis criteria. Association of oligohydramnios, kidney agenesis and CHAOS should lead to consider this diagnosis. © 2016 John Wiley & Sons, Ltd.

Abstract
Background Fraser Syndrome is a rare, autosomal recessive syndrome. It’s characterized primarily by cryptophthalmos, syndactyly and urogenital malformation. Respiratory malformations are frequently present and not taken into account. To better manage childbirth at the time of delivery it is crucial to get prenatal diagnosis early on in the pregnancy. Case presentation We are reporting a female infant born by natural birth with 46,XX. She was characterized phenotypically by cryptophthalmos, syndactyly, bilateral microtia and ambiguous genitalia. A prenatal ultrasound didn’t revealed or raised any suspects for the Fraser Syndrome. It only discovered a unilateral kidney agenesis. At birth the infant showed a severe respiratory distress, intubation was attempted but it failed. The baby was transferred to Santobono-Pausilipon III level hospital. A tracheostomy was performed successfully and saved her life. Computerized Tomography revealed left microphthalmos and a malformation like-coloboma into right ocular globe with cysts and a small calcification parietal anterior. Genetic test revealed the typical mutations in the gene FREM2 confirming the diagnosis of Fraser Syndrome. In her fourth month, after birth, the infant was subjected to an operation to reconstruct eyelids with a mucous membrane graft. The left renal function was normal. The baby showed a delay in motor milestones for visual impairment. At the 19th month fallow-up, during a magnetic resonance it was revealed: a normal morphologic brain development, a thin presence in the right optic nerve and the visual cortex were developing. Conclusions The prenatal diagnosis of Fraser Syndrome is frequently possible. The prenatal ultrasound can reveal features like polyhydramnios or oligohydramnios, echogenic lungs, renal abnormalities or agenesis and cryptophthalmos that are pathognomonic of the Fraser Syndrome. The health providers must keep in mind that if there are suspects of the Fraser Syndrome during prenatal exams, the infants could have a severe malformation in the respiratory tract.

Abstract
Fraser syndrome is a rare autosomal recessive disorder characterized by cryptophthalmos, cutaneous syndactyly, laryngeal, and urogenital malformations. We present a population-based epidemiological study using data provided by the European Surveillance of Congenital Anomalies (EUROCAT) network of birth defect registries. Between January 1990 and December 2008, we identified 26 cases of Fraser syndrome in the monitored population of 12,886,464 births (minimal estimated prevalence of 0.20 per 100,000 or 1:495,633 births). Most cases (18/26; 69%) were registered in the western part of Europe, where the mean prevalence is 1 in 230,695 births, compared to the prevalence 1 in 1,091,175 for the rest of Europe (P = 0.0003). Consanguinity was present in 7/26 (27%) families. Ten (38%) cases were liveborn, 14 (54%) pregnancies were terminated following prenatal detection of a serious anomaly, and 2 (8%) were stillborn. Eye anomalies were found in 20/24 (83%), syndactyly in 14/24 (58%), and laryngeal anomalies in 5/24 (21%) patients. Ambiguous genitalia were observed in 3/24 (13%) cases. Bilateral renal agenesis was present in 12/24 (50%) and unilateral in 4/24 (17%) cases. The frequency of anorectal anomalies was particularly high (42%). Most cases of Fraser syndrome (85%) are suspected prenatally, often due to the presence of the association of renal agenesis and cryptophthalmos. In the European population, a high proportion (82%) of pregnancies is terminated, thus reducing the live birth prevalence to a third of the total prevalence rate.
