OBJECTIVE:
To analyze the phenotype and genetic variant of a fetus with dysplasia of cerebellar vermis.
METHODS:
Gestational status and family history of the gravida was taken in combination with the imaging results of the fetus. Following elected abortion, fetal tissue and peripheral blood samples of the couple were collected for the extraction of genome DNA. Whole exome sequencing was carried out to screen potential variant associated with the phenotype of the proband. Specific PCR primers were designed to verify the results by Sanger sequencing.
RESULTS:
Prenatal ultrasound revealed that the fetal vermis cerebellum was poorly developed, which was similar to the previous pregnancy. Whole exome sequencing revealed that the fetus has carried compound heterozygous variants of the CPLANE1 gene, namely c.7978C>T and c.7169delT, which were respectively inherited from the husband and wife.
CONCLUSION
The c.7978C>T and c.7169delT compound heterozygous variants of the CPLANE1 gene probably underlay the dysplasia of cerebellar vermis in the fetus, which has provided a basis for genetic counseling and prenatal diagnosis.

OBJECTIVE:
To analyze clinical and genetic features of a family affected with Van der Woude syndrome.
METHODS:
The umbilical cord blood of the proband and the peripheral blood of the parents were used for the whole exon sequencing to find the candidate gene.Peripheral blood of 9 members of the family were collected for Sanger sequencing verification, bioinformatics analysis and genotype-phenotype correlation analysis.
RESULTS:
The proband was diagnosed with cleft lip and palate by ultrasound. His father and grandmother had hollow lower lip and all other family members did not have the similar phenotype. A missense c.263A>G (p.N88S) mutation was found in exon 4 of gene in the proband, his father and his grandmother.The mutation was not found in other family members.
CONCLUSIONS
A missense c.263A>G (p.N88S) mutation in gene probably underlies the pathogenesis of Van der Woude syndrome in the family and the mutation has been firstly discovered in China.

Levocardia (left-sided cardiac apex) with abdominal situs inversus is extremely rare. This is also known as isolated levocardia and is almost always associated with severe forms of congenital heart defects with poor prognosis. We report isolated levocardia in a 13-year-old symptomatic male patient. The purpose of this paper is to outline the imaging features of isolated levocardia and to highlight the role of cardiovascular magnetic resonance imaging (CMR) in the diagnosis and management of such cases. Other forms of cardiac malposition, including dextrocardia, mesocardia and criss-cross heart, with chest radiograph and CMR correlation, are also discussed.

OBJECTIVETo study the clinical characteristics and diagnostic methods of rare autosomal recessive inherited Bardet-Biedl syndrome in patients presented with renal abnormalities.
METHODComprehensive analyses were performed on data of 4 confirmed Bardet-Biedl syndrome cases seen at nephrology department of Beijing Children Hospital affiliated to Capital Medical University, including clinical features, laboratory examination and diagnostic criteria.
RESULT(1) Four cases were confirmed to meet Bardet-Biedl syndrome diagnostic criteria (male: female = 1: 1): first diagnosis age was 10 y, 9 y 8 m, 10 y 10 m, 8 y 2 m. (2) Cases 1, 2, and 3 had a history of polyuria and polydipsia, cases 4 began with edema and oliguria. (3) All had slight change in urine routine test. Case 3 and Case 4 were presented with small to medium amount of proteinuria. None had microscopic hematuria. (4) All had different degree of renal injury, Case 1 and 3 were at the third phase of chronic kidney disease (CKD), Case 4 was at the fourth phase of CKD, Case 4 was at the fifth phase of CKD and needed dialysis. (5) All cases had obvious abnormalities of urinary tract ultrasound, 3 of them had chronic diffuse lesions with cyst formation of both kidneys. The rest one had dysplasia of right kidney and fused kidney. (6) All cases were presented with vision loss with 100% of electroretinogram abnormalities and 50% of fundus examination abnormalities. (7) Three cases were presented with obesity. (8) Multiple organs were involved in all cases, including electrocardiographic abnormality and/or thickening of the left ventricular wall (4/4) , polydactyly (2/4) , small penis and testicles (2/4) and short stature (2/4) .
CONCLUSIONClinical manifestations of Bardet-Biedl syndrome (BBS) conceals, routine urine test changes slightly, abnormalities of renal structure and (or) tubular interstitial function is a typical manifestation of children with BBS. Urinary tract ultrasound screening may show diffuse lesions with double kidney with cyst formation or structural abnormalities. Clinical manifestation accompany with retinal degeneration, obesity, myocardial involvement, polydactyly, and hypogonadism.

OBJECTIVETo screen for genomic copy number variations (CNVs) in two unrelated neonates with multiple congenital abnormalities using Affymetrix SNP chip and try to find the critical region associated with congenital heart disease.
METHODTwo neonates were tested for genomic copy number variations by using Cytogenetic SNP chip.Rare CNVs with potential clinical significance were selected of which deletion segments' size was larger than 50 kb and duplication segments' size was larger than 150 kb based on the analysis of ChAs software, without false positive CNVs and segments of normal population. The identified CNVs were compared with those of the cases in DECIPHER and ISCA databases.
RESULTEleven rare CNVs with size from 546.6-27 892 kb were identified in the 2 neonates. The deletion region and size of case 1 were 8p23.3-p23.1 (387 912-11 506 771 bp) and 11.1 Mb respectively, the duplication region and size of case 1 were 8p23.1-p11.1 (11 508 387-43 321 279 bp) and 31.8 Mb respectively. The deletion region and size of case 2 were 8p23.3-p23.1 (46 385-7 809 878 bp) and 7.8 Mb respectively, the duplication region and size of case 2 were 8p23.1-p11.21 (12 260 914-40 917 092 bp) and 28.7 Mb respectively. The comparison with Decipher and ISCA databases supported previous viewpoint that 8p23.1 had been associated with congenital heart disease and the region between 7 809 878-11 506 771 bp may play a role in the severe cardiac defects associated with 8p23.1 deletions. Case 1 had serious cardiac abnormalities whose GATA4 was located in the duplication segment and the copy number increased while SOX7 was located in the deletion segment and the copy number decreased.
CONCLUSIONThe region between 7 809 878-11 506 771 bp in 8p23.1 is associated with heart defects and copy number variants of SOX7 and GATA4 may result in congenital heart disease.

OBJECTIVETo explore clinical, radiographical and genetic characteristics of classical Hutchinson-Gilford progeria syndrome (HGPS).
METHODData of a case of HGPS diagnosed at Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology was analyzed and related literature was reviewed.
RESULTAt the age of 8 months, the affected-infant presented with characteristic manifestation such as short stature, low weight, frontal bossing, alopecia, prominent scalp veins, micrognathia with a vertical midline groove in the chin, sclerodermatous skin, knee joints contracture with a horse-riding stance, and limited range of movement of ankle joints. Blood test showed blood platelet count (416-490) ×10(9)/L. Lower extremities MRI showed reduced subcutaneous fat. LMNA gene analysis showed that the affected-infant carried typical heterozygous mutation: c. 1824C>T (p. G608G), while his parents were normal. At the age of 13 months, X-rays showed short distal phalanges and clavicles with acro-osteolysis. After following up for 15 months, his appearance of progeria became more apparent. As far as we know, there are only 2 cases of classical HGPS confirmed by gene analysis in China.
CONCLUSIONClassical HGPS should be considered when infants appeared with sclerodermatous skin. Genetic analysis could help to diagnose classical HGPS as early as possible and avoid unnecessary investigations. In addition, affected-infants need to be long term followed-up and provided genetic counseling.

OBJECTIVETo investigate the clinical characteristics, diagnosis and therapy of Keutel syndrome, and thereby to minimize the misdiagnosis.
METHODData of a case of Keutel syndrome diagnosed at the Provincial Hospital Affiliated to Shandong University were analyzed and related literature were reviewed.
RESULTAn 8-month-26-day-old boy was presented with inspiratory and expiratory stridor and wheezing after movement on lung auscultation. His craniofacial appearance was characterized by midfacial hypoplasia with a broad depressed nasal bridge. The nose was small and flat. A grade 2-3/6 systolic murmur was heard between the second and third ribs at left edge of the sternum. The end phalanges of his fingers were thickened. Chest radiograph showed tracheobronchial cartilage calcification and tracheobronchial stenosis. Echocardiographic examination revealed the right pulmonary stenosis. With endoscopic surgery, antiobstructive and antibiotic therapy clinical symptoms were improved. Three weeks later he died of lung reinfection after he was discharged from our hospital. English literature search with "Keutel syndrome" as the key word at "PubMed" showed 22 articles covering 26 patients, and the clinical symptoms were hearing loss (91%), persistent respiratory symptoms (68%), recurrent otitis media/sinusitis (67%), growth development delay (52%) in turn, and signs were brachytelephalangism (100%), low nasal bridge (95%), midfacial hypoplasia (93%), cardiac murmur (69%), and auxiliary examinations showed abnormal cartilage calcification (100%), pulmonary arterial stenosis (72%), tracheobronchial stenosis (50%).
CONCLUSIONThe diagnosis of Keutel syndrome should be considered in patients with brachytelephalangism, abnormal cartilage calcification, peripheral pulmonary stenosis, and midfacial hypoplasia. Tracheal stenosis was main clinical manifestation in part of patients.
