Study of two families containing individuals with nephrogenic diabetes insipidus (NDI) indicated different types of 21.3 kb and 26.3 kb deletions involving the AVPR2 and ARHGAP4 (RhoGAP C1) genes. In the case of the 21.3 kb deletion, the deletion consensus motif (5'-TGAAGG-3') and polypurine runs, known as the arrest site of polymerase alpha, were detected(More)
Anomalous origin of the coronary artery can lead to angina pectoris, acute myocardial infarction or even sudden death in the absence of atherosclerosis. However, in Japan, this anomaly is usually treated medically rather than surgically. To clarify the clinical features of anomalous origin of the coronary artery in Japanese and the prognosis of such(More)
Genetic determinants of HDL cholesterol (HDL-C) levels in the general population are poorly understood. We previously described plasma cholesteryl ester transfer protein (CETP) deficiency due to an intron 14 G(+1)-to-A mutation(Int14 A) in several families with very high HDL-C levels in Japan. Subjects with HDL-C > or = 100 mg/dl (n = 130) were screened by(More)
Lipoprotein patterns and cholesteryl ester transfer activity (CETA) were examined in 2 patients with familial hyperalphalipoproteinaemia (FHALP). The proband was a healthy 58-year-old Japanese male who had an HDL cholesterol of 7.83 mmol/l (301 mg/dl). His sister's HDL cholesterol was 4.52 mmol/l (174 mg/dl), which suggested that both were homozygous(More)
BACKGROUND AND METHODS The plasma cholesteryl-ester transfer protein (CETP) catalyzes the transfer of cholesteryl esters from high-density lipoprotein (HDL) to other lipoproteins. We recently described a Japanese family with increased HDL levels and CETP deficiency due to a splicing defect of the CETP gene. To assess the frequency and phenotype of this(More)
QT dispersion (QTD) on 12-lead ECGs has been proposed as a marker of malignant ventricular tachyarrhythmias, and increased QTD has been reported in long QT syndrome (LQTS). On the other hand, it has been demonstrated that transmural dispersion is associated with ventricular tachyarrhythmias in an experimental model. However, the precise type of QTD or(More)
Plasma high density lipoproteins (HDL) are a negative risk factor for atherosclerosis. Increased HDL is sometimes clustered in families, but a genetic basis has never been clearly documented. The plasma cholesteryl ester transfer protein (CETP) catalyses the transfer of cholesteryl ester from HDL to other lipoproteins and therefore might influence HDL(More)
This paper described the Guideline for Diagnosis and Management of Hyperlipidemias for Prevention of Atherosclerosis proposed by The Japan Atherosclerosis Society (JAS) Guideline Investigating Committee (1,995-2,000) under the auspices of the JAS Board of Directors. 1) The guideline defines the diagnostic criteria for serum total cholesterol (Table 1),(More)
An elevated level of low-density lipoprotein (LDL)-cholesterol has been recognised as the most important risk factor for coronary artery disease (CAD). Development of the inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) ('statins'), a rate-limiting key enzyme of cholesterol synthesis pathway, has revolutionised the cholesterol-lowering therapy.(More)
BACKGROUND Use of genetic analysis may improve the predictive value of risk factors for disease. A high plasma level of high-density lipoprotein (HDL) cholesterol is a strong negative risk factor for coronary heart disease (CHD). Cholesteryl ester transfer protein (CETP) deficiency causes increased levels of HDL cholesterol. However, recent studies suggest(More)
