Genetic Susceptibility to Transient and Permanent Neonatal Diabetes Mellitus
Neonatal diabetes mellitus (NDM) is a rare kind of diabetes characterized by hyperglycemia and low levels of insulin. Clinically, it is categorized into two main types: transient NDM (TNDM) and permanent NDM (PNDM). These types are diagnosed based on duration of insulin dependence early in the disease. In TNDM, diabetes begins in the first few weeks of life with remission in a few months. Howev...
متن کاملTransient neonatal diabetes mellitus caused by a de novo ABCC8 gene mutation
Transient neonatal diabetes mellitus (TNDM) is a rare form of diabetes mellitus that presents within the first 6 months of life with remission in infancy or early childhood. TNDM is mainly caused by anomalies in the imprinted region on chromosome 6q24; however, recently, mutations in the ABCC8 gene, which encodes sulfonylurea receptor 1 (SUR1), have also been implicated in TNDM. Herein, we pres...
متن کاملTransient Neonatal Diabetes Mellitus in a Very Preterm Infant due to ABCC8 Mutation
Neonatal diabetes mellitus (NDM) is a monogenic form of diabetes occurring within 6 months from birth. NDM can be permanent or transient (TNDM). We report the case of a preterm infant with TNDM due to an ABCC8 mutation identified by next-generation sequencing. The pancreatic adenosine triphosphate (ATP)-sensitive K+ (K-ATP) channel is a key regulator of insulin secretion. Gain-of-function mutat...
متن کاملNeonatal Diabetes
Context: Neonatal diabetes mellitus, a rare condition occurring in approximately 1 in 500 000 live births, is defined as insulin-requiring hyperglycemia presenting in the first months of life. Neonatal diabetes can be transient or permanent, with studies characterizing the condition as a monogenic disorder. Case Report: We describe a case of a 9-week-old infant with neonatal diabetes who presen...
متن کاملNew ABCC8 mutations in relapsing neonatal diabetes and clinical features.
Activating mutations in the ABCC8 gene that encodes the sulfonylurea receptor 1 (SUR1) regulatory subunit of the pancreatic islet ATP-sensitive K(+) channel (K(ATP) channel) cause both permanent and transient neonatal diabetes. Recently, we have described the novel mechanism where basal Mg-nucleotide-dependent stimulatory action of SUR1 on the Kir6.2 pore is increased. In our present study, we ...
متن کاملPermanent neonatal diabetes mellitus due to an ABCC8 mutation: a case report.
CONTEXT Neonatal diabetes is a rare disorder with an incidence of about 1 in 100,000 live births. It is defined as diabetes diagnosed in the first 6 months of life and it is vital to differentiate this entity from type 1 diabetes to enable accurate diagnosis, prognosis, genetic counseling and treatment. CASE REPORT We describe a case of permanent neonatal diabetes mellitus due to a novel muta...
