Cleft palate and congenital alveolar synechia is a rare syndrome. Only eight cases have been previously reported. It consists of a spectrum of facial anomalies always including cleft palate and congenital alveolar synechiae without other abnormalities. This report described an unusual case of congenital alveolar synechial band spanning posterior alveolar of the two jaws with cleft palate. Previously reported cases showed bilaterally or anteriorly located fibrous band. In our department, a new born revealed unilateral posterior synechia. Under brief intravenous sedation, synechium was divided using bipolar diathermy in the nursery at 3 days of age because of poor feeding. This division allowed full jaw opening after brief passive exercise. The patient is growing and maturing as expected with no complications. This patient is supposed to be the first reported case of isolated unilateral alveolar synechium combined with cleft palate in the worldwide.

Abnormalities of structure and morphology of chromosomes concentrated with genetic materials, DNA, are directly related to phenotypical performances of animals. So, cytogenetical research in domestic animals is important to prevent congenital deformity and improve genetic performances. Especially utilities of egg transfer technique combined with cytogenetical study can be accelerated by the wide spread of the best genetic sources dependent on the micromanipulation and sexing of eggs.

Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9 (CRISPR-Cas9) is an ancient prokaryotic defense system that precisely cuts foreign genomic DNA under the control of a small number of guide RNAs. The CRISPR-Cas9 system facilitates efficient double-stranded DNA cleavage that has been recently adopted for genome editing to create or correct inherited genetic mutations causing disease. Congenital heart disease (CHD) is generally caused by genetic mutations such as base substitutions, deletions, and insertions, which result in diverse developmental defects and remains a leading cause of birth defects. Pediatric CHD patients exhibit a spectrum of cardiac abnormalities such as septal defects, valvular defects, and abnormal chamber development. CHD onset occurs during the prenatal period and often results in early lethality during childhood. Because CRISPR-Cas9-based genome editing technology has gained considerable attention for its potential to prevent and treat diseases, we will review the CRISPR-Cas9 system as a genome editing tool and focus on its therapeutic application for CHD.

Congenital midline cervical cleft is a rare congenital disease. The disease is often misdiagnosed as a branchial cleft deformity, thyroglossal duct cyst, or other skin diseases. It has the following characteristics: skin defect at the midline of the anterior neck, a skin tag at the upper end of the lesion, and a blind sinus tract at the caudal aspect with or without mucoid discharge. Treatment is usually for aesthetic purposes; therefore, early surgical en bloc resection with Z-plasty or W-plasty is recommended to reduce recurrence and scar formation.

목 적 : 본 연구는 단일 기관에서 혈역학적으로 의미 있는 선천성 심기형을 가진 극소 저체중 출생아의 임상경과와 치료성적 및 예후 인자를 알아보고자 하였다. 방 법 : 1994년 11월부터 2007년 12월까지 13년간 삼성서울병원 신생아 집중치료실에 입원하였던 출생 체중 1,500 g 미만의 극소 저체중 출생아 1,098명을 대상으로 의무기록을 후향적으로 조사하였다. 선천성 심기형을 가진 대상아 33명의 임상경과, 합병증, 예후를 조사하였고 이들을 대조군 1,065명과 비교하였다. 결 과 : 총 극소 저체중 출생아 1,098명 중 33명(3%)에서 선천성 심기형이 있었으며, 이들 중 7명(21%)에서 선천기형 및 염색체 이상을 동반하였다. 심기형 종류로는 심실 중격 결손이 21명(64%)으로 가장 많았다. 자궁 내 성장 지연은 심기형군이 대조군에 비해 높았으나(34% vs. 20%), 재태기간, 출생체중, 신생아 호흡 곤란 증후군, 기관지폐 형성 이상, 괴사성 장염, 뇌실내 출혈, 그리고 낭종성 뇌실주위 백질 연화증의 빈도는 심기형군과 대조군 사이에 차이가 없었다. 심장수술은 단순 심기형에서 4명(19%), 복합 심기형에서 9명(75%)에게 시행되었고, 9명(69%)이 다단계 수술을, 10명(77%)은 조기 중재시술을 받았다. 심기형군의 사망률은 대조군에 비해 증가되어 있었고(27% vs. 16%), 특히 염색체 이상 및 다발성 기형을 동반한 경우에만 증가되었고(86% vs. 11%), 그 외 단순, 복합 심기형 여부(19% vs. 42%)와는 상관관계가 없었다. 결 론 : 극소 저체중 출생아에서 발생한 선천성 심기형의 예후는 심기형 자체의 복합성 보다는 동반된 선천 기형 및 염색체 이상이 결정한다.

호흡곤란을 주소로 내원한 17세 환자가 대동맥 및 폐동맥 사엽성 판막을 보이며 심방중격결손과 폐동맥 판막 협착증이 발전되어 소심막을 이용한 심방중격결손 봉합 및 폐동맥 판막 교련절개술을 시행하였다. 대동맥 판막과 폐동맥 판막이 모두 사엽성 판막을 보이는 경우는 매우 드문 선천성 기형으로 폐동맥 사엽성 판막이 대동맥 사업성 판막보다 9배정도 많다. 본 증례는 Hurwitz and Roberts 분류법상 대동맥판막은 A형, 폐동맥판막은 B형이었으며 대동맥 판막기능은 정상적이었고 폐동맥 판막 협착증을 보였다.

Septo-optic dysplasia is a congenital anomaly with diverse phenotypes from normal to mixtures of visual abnormality, endocrine dysfunction, psychomotor retardations and epileptic seizures. It is characterized by optic atrophy, pituitary dysfunction and midline structure abnormalities in corpus callosum or septum pellucidum. Diagnosis of septo-optic dysplasia plus is made when cortical malformations accompanied. Here we report a middle-aged woman with septo-optic dysplasia plus having unilateral optic atrophy, agenesis of septum pellucidum and cortical malformations.

Kabuki syndrome (KS) is a rare syndrome characterized by multiple congenital anomalies and mental retardation. Other characteristics include a peculiar facial gestalt, short stature, skeletal and visceral abnormalities, cardiac anomalies, and immunological defects. Whole exome sequencing has uncovered the genetic basis of KS. Prior to 2013, there was no molecular genetic information about KS in Korean patients. More recently, direct Sanger sequencing and exome sequencing revealed KMT2D variants in 11 Korean patients and a KDM6A variant in one Korean patient. The high detection rate of KMT2D and KDM6A mutations (92.3%) is expected owing to the strict criteria used to establish a clinical diagnosis. Increased awareness and understanding of KS among clinicians is important for diagnosis and management of KS and for primary care of KS patients. Because mutation detection rates rely on the accuracy of the clinical diagnosis and the inclusion or exclusion of atypical cases, recognition of KS will facilitate the identification of novel mutations. A brief review of KS is provided, highlighting the clinical and genetic characteristics of patients with KS.

Bladder exstrophy is a rare congenital condition of the pelvis, bladder, and lower abdomen that opens the bladder against the abdominal wall, produces aberrant growth, short penis, upward curvature during erection, wide penis, and undescended testes. Exstrophy affects 1/30,000 newborns. The bladder opens against the abdominal wall in bladder exstrophy, a rare genitourinary condition. This study is vital to provide appropriate therapy choices as a basis to improve patient outcomes. This study may explain bladder exstrophy and provide treatment. Epispadias, secretory placenta, cloacal exstrophy, and other embryonic abnormalities comprise the exstrophy-spades complex. The mesenchymal layer does not migrate from the ectoderm and endoderm layers in the first trimester, affecting the cloacal membrane. Embryological problems define the exstrophy-aspidistra complex, which resembles epimedium, classic bladder, cloacal exstrophy, and other diseases. Urogenital ventral body wall anomalies expose the bladder mucosa, causing bladder exstrophy. Genetic mutations in the Hedgehog cascade pathway, Wnt signal, FGF, BMP4, Alx4, Gli3, and ISL1 cause ventral body wall closure and urinary bladder failure. External factors such as high maternal age, smoking moms, and high maternal body mass index have also been associated to bladder exstrophy. Valproic acid increases bladder exstrophy risk; chemicals and pollutants during pregnancy may increase bladder exstrophy risk. Bladder exstrophy has no identified cause despite these risk factors. Exstrophy reconstruction seals the bladder, improves bowel function, reconstructs the vaginal region, and restores urination.
