Guidelines for 22q11 deletion screening of patients with conotruncal defects.
Goldmuntz et al. (1) have reported the frequency of 22q11 deletions in a prospectively ascertained sample of 251 patients with conotruncal defects. Deletions were found in 17.9% of the patients, including 50% with interrupted aortic arch (IAA), 34.3% with truncus arteriosus (TA), and 15.9% with tetralogy of Fallot (TOF). Although this study was designed to determine the frequency of deletions i...
متن کاملChromosome 10p13-14 and 22q11 deletion screening in 100 patients with isolated and syndromic conotruncal heart defects.
Heart defects are among the most common congenital anomalies, occurring in approximately 1% of newborn populations. Conotruncal heart defects (CTHD), which account for 50-60% of all congenital heart malformations, are known to have a strong genetic component. They occur either as an isolated malformation or in association with extracardiac anomalies. In particular, CTHD constitute a cardinal co...
متن کاملIdentification of two novel GATA6 mutations in patients with nonsyndromic conotruncal heart defects.
GATA binding protein 6 (GATA6) encodes a zinc‑finger transcription factor that is essential for normal heart development. Mutations in this gene lead to conotruncal heart defects associated with cyanotic congenital heart disease; however, it remains unclear whether the mutations in GATA6 are also responsible for the development of the nonsyndromic conotruncal heart defects. The coding region exo...
متن کاملCFTR founder mutation causes protein trafficking defects in Chinese patients with cystic fibrosis
BACKGROUND Cystic fibrosis (CF) is a rare condition in Asians. Since 1985, only about 30 Chinese patients have been reported with molecular confirmation. METHOD Using our in-house next-generation sequencing (NGS) pipeline for childhood bronchiectasis, we identified disease-causing CFTR mutations in CF patients in Hong Kong. After identifying p.I1023R in multiple patients, haplotype analysis w...
متن کاملNovel loss-of-function PRRT2 mutation causes paroxysmal kinesigenic dyskinesia in a Han Chinese family
BACKGROUND Mutations in proline-rich transmembrane protein 2 (PRRT2) are a cause of paroxysmal kinesigenic dyskinesia (PKD). In this study, we investigated the PRRT2 gene mutation in a Chinese Han family with PKD and study the pathogenesis of the mutation with PRRT2 gene. METHODS Peripheral venous blood was taken from the family members. Sanger sequencing was used for novel mutation sequencin...
