Neonatal hypoglycemia due to congenital hyperinsulinism (CHI) is a potentially life-threatening condition. Biallelic pathogenic variants in KATP channel subunit genes (ABCC8, KCNJ11), causing severe forms of CHI, are more prevalent in regions with a significant rate of consanguinity and may lead to unexplained neonatal deaths. We hypothesized that KATP channel gene variants are the cause of CHI in three unrelated children from consanguineous Kurdish families with histories of four unexplained neonatal deaths with convulsions.

Cantu Syndrome (CS) is a complex disorder caused by gain-of-function (GoF) mutations in ABCC9 and KCNJ8, which encode the SUR2 and Kir6.1 subunits, respectively, of vascular smooth muscle (VSM) KATP c...
The ATP-sensitive K+ channel (KATP) is formed by the association of four inwardly rectifying K+ channel (Kir6.x) pore subunits with four sulphonylurea receptor (SUR) regulatory subunits. Kir6.x or SUR...
Major advances have been made in the genetics and classification of congenital hyperinsulinism (CHI).
A girl was admitted to the hospital on day 2 after birth due to jaundice of the skin and sclera for half a day. The main clinical manifestations were persistent severe jaundice and thrombocytopenia, a...
Autosomal recessive congenital ichthyosis is a genetically and phenotypically heterogenous group of scaling skin disorders. We describe a patient with ARCI caused by homozygous variants in NIPAL4, in ...
The purpose of this pilot study is to generate data to assess feasibility of study design/procedures and for formal sample size estimation for a larger multicenter study of the efficacy an...
Congenital hyperinsulinism is a rare condition that can cause life-threatening hypoglycemia. Current treatment for congenital hyperinsulinism is often suboptimal, and such individuals may ...
The purpose of this study is to determine if Exendin-(9-39), an antagonist of the glucagon-like peptide-1 (GLP-1) receptor with effects on the pancreatic beta cell, increases fasting bloo...
The goal of this project is to determine the role of FDOPA/PET as a pre-operative diagnostic imaging procedure for differentiating focal and diffuse forms of congenital hyperinsulinism and...
Children with congenital hyperinsulinism have low blood sugar, and some of these children may require surgery. In this study, researchers affiliated with the University of Pennsylvania wil...
Heteromultimers of Kir6 channels (the pore portion) and sulfonylurea receptor (the regulatory portion) which affect function of the HEART; PANCREATIC BETA CELLS; and KIDNEY COLLECTING DUCTS. KATP channel blockers include GLIBENCLAMIDE and mitiglinide whereas openers include CROMAKALIM and minoxidil sulfate.
A form of long QT syndrome that is without congenital deafness. It is caused by mutation of the KCNQ1 gene which encodes a protein in the VOLTAGE-GATED POTASSIUM CHANNEL.
A form of long QT syndrome that is associated with congenital deafness. It is characterized by abnormal cardioelectrophysiology involving the VOLTAGE-GATED POTASSIUM CHANNEL. It results from mutation of KCNQ1 gene (Subtype 1 or JLN1) or the KCNE1 gene (Subtype 2 or JLN2).
The percent frequency with which a dominant or homozygous recessive gene or gene combination manifests itself in the phenotype of the carriers. (From Glossary of Genetics, 5th ed)
A voltage-gated sodium channel subtype that mediates the sodium ion PERMEABILITY of CARDIOMYOCYTES. Defects in the SCN5A gene, which codes for the alpha subunit of this sodium channel, are associated with a variety of CARDIAC DISEASES that result from loss of sodium channel function.
Congenital conditions are those which are present from birth. They include structural deformities or loss of function in organs such as the <!--LGfEGNT2Lhm-->heart, gut or skeletal system. They can be corrected by <!--LGfEGNT2Lhm-->surgery, m...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
