BACKGROUND Smoking is a risk factor for many human diseases. DNA methylation has been related to smoking, but genome-wide methylation data for smoking in Chinese populations is limited. OBJECTIVES We aimed to investigate epigenome-wide methylation in relation to smoking in a Chinese population. METHODS We measured the methylation levels at > 485,000 CpG(More)
BACKGROUND When compared to the other mismatch repair genes involved in Lynch syndrome, the identification of mutations within PMS2 has been limited (<2% of all identified mutations), yet the immunohistochemical analysis of tumour samples indicates that approximately 5% of Lynch syndrome cases are caused by PMS2. This disparity is primarily due to(More)
OBJECTIVE To identify the underlying androgen receptor gene mutation in a Chinese patient with typical symptoms of complete androgen insensitivity syndrome. STUDY DESIGN A Chinese female phenotype with 46, XY karyotype was diagnosed because of primary amenorrhea. Mutations were determined by polymerase chain reaction followed by DNA sequencing. RESULTS(More)
OBJECTIVE To analyze the coding sequence of GJB2 gene in six pedigrees with nonsyndromic hearing loss in order to find deafness-causing mutations in the GJB2 gene, and to explore the inherent pattern of deafness-causing mutations in the GJB2 gene. METHODS Genomic DNA was extracted from peripheral blood for the probands and their family members. Coding(More)
OBJECTIVE To analyze potential mutations of uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) gene in patients with unconjugated hyperbilirubinemia, and to explore the correlation between the mutations and total serum bilirubin levels. METHODS Genomic DNA was extracted from peripheral blood samples of patients. Coding sequence and promoter region(More)
Distal trisomy of 10q is a rare chromosomal abnormality. Distal deletions of the terminal long arm of chromosome 15 have rarely been described. We report on a male infant with low birth weight and microcephaly, a flat face with a spacious forehead, low-set ears, blepharophimosis, microphthalmia, a small nose, and a depressed nasal bridge. Microarray(More)
OBJECTIVE To investigate the D4Z4 repeats on chromosome 4q35 in normal individuals in Shanghai and analysis the polymorphism of the D4Z4 locus. METHODS The length of D4Z4 repeats on chromosome 4q35 in 191 normal individuals in Shanghai was determined by pulsed-field gel electrophoresis and Southern blotting after double digestion with Eco RI and Bln I.(More)
This study was aimed to analyze the β-globin gene mutations in a patient with β-thalassemia minor. Genomic DNA was extracted from peripheral blood cells of the patient. The full-length DNA sequence coding for β-globin was amplified by polymerase chain reaction, and the gene mutation was determined by DNA sequencing. The results indicated that a(More)
OBJECTIVE To find the length and location of the deletions in the short arm of chromosome 5 in one case of Cri du Chat syndrome using oligo array comparative genomic hybridization. METHODS Metaphase chromosomes were prepared from peripheral blood lymphocyte cultures using standard cytogenetic protocols. Chromosomal analysis was done in G-banded(More)
RATIONALE Acute coronary syndrome (ACS) is a leading cause of death worldwide. Immune functions play a vital role in ACS development; however, whether epigenetic modulation contributes to the regulation of blood immune cells in this disease has not been investigated. OBJECTIVE We conducted an epigenome-wide analysis with circulating immune cells to(More)
