CONTEXT Diabetes in neonates nearly always has a monogenic etiology. Earlier sulfonylurea therapy can improve glycemic control and potential neurodevelopmental outcomes in children with KCNJ11 or ABCC8 mutations, the most common gene causes. OBJECTIVE Assess the risks and benefits of initiating sulfonylurea therapy before genetic testing results become(More)
OBJECTIVE To evaluate the cost-effectiveness of a genetic testing policy for HNF1A-, HNF4A-, and GCK-MODY in a hypothetical cohort of type 2 diabetic patients 25-40 years old with a MODY prevalence of 2%. RESEARCH DESIGN AND METHODS We used a simulation model of type 2 diabetes complications based on UK Prospective Diabetes Study data, modified to account(More)
AIMS/HYPOTHESIS Individuals with heterozygous activating mutations of the KCNJ11 gene encoding a subunit of the ATP-sensitive potassium channel (KATP) can usually be treated with oral sulfonylurea (SU) pills in lieu of insulin injections. The aim of this study was to test our hypothesis that younger age at the time of initiation of SU therapy is correlated(More)
Single gene mutations that primarily affect pancreatic β-cell function account for approximately 1-2% of all cases of diabetes. Overlapping clinical features with common forms of diabetes makes diagnosis of monogenic diabetes challenging. A genetic diagnosis often leads to significant alterations in treatment, allows better prediction of disease prognosis(More)
Chromosome 6q24-related transient neo-natal diabetes (6q24-TND) is a rare form of diabetes caused by an overexpression of PLAGL1 and HYMAI (1). After remitting in infancy, diabetes recurs in most patients later in life. While the best treatment remains unknown, many patients are managed with insulin (1). We sought to characterize b-cell function and glucose(More)
GCK-MODY leads to mildly elevated blood glucose typically not requiring therapy. It has been described in all ethnicities, but mainly in Caucasian Europeans. Here we describe our US cohort of GCK-MODY. We examined the rates of detection of heterozygous mutations in the GCK gene in individuals referred to the US Monogenic Diabetes Registry with a phenotype(More)
Neonatal diabetes mellitus is known to have over 20 different monogenic causes. A syndrome of permanent neonatal diabetes along with primary microcephaly with simplified gyral pattern associated with severe infantile epileptic encephalopathy was recently described in two independent reports in which disease-causing homozygous mutations were identified in(More)
Counterterrorism specialists and law enforcement agencies are interested in the long-term intent or plans of the terrorists and Organized Crime members that they oppose. They often get only sporadic, incomplete, or seemingly unrelated secondhand information upon which to base their reasoning.. Some aspects of terrorist behavior are quite repetitive and(More)
BACKGROUND Diabetes in neonates usually has a monogenic aetiology; however, the cause remains unknown in 20-30%. Heterozygous INS mutations represent one of the most common gene causes of neonatal diabetes mellitus. METHODS Clinical and functional characterisation of a novel homozygous intronic mutation (c.187+241G>A) in the insulin gene in a child(More)
BACKGROUND Glucokinase related maturity-onset diabetes of the young (GCK-MODY) is a form of monogenic diabetes characterized by mildly elevated fasting blood sugars and HbA(1c) typically ranging from 38 to 60 mmol/mol (5.6-7.6%). It is frequently unrecognized or misdiagnosed as Type 1 or Type 2 diabetes, resulting in unnecessary pharmacologic therapy. (More)
