Background: Pathophysiology of type 2 diabetes mellitus (T2DM) is influenced by the complex interaction several genes that regulate energy metabolism in body. Several polymorphisms occur many gene encode components glucose regulation are significantly implicated onset T2DM.Methods: This case-control study. Case group with 58 subjects T2DM patients obesity and a control non-DM obese from ethnic ...

We have recently shown that permanent neonatal diabetes can be caused by activating mutations in KCNJ11 that encode the Kir6.2 subunit of the beta-cell ATP-sensitive K(+) channel. Some of these patients were diagnosed after 3 months of age and presented with ketoacidosis and marked hyperglycemia, which could have been diagnosed as type 1 diabetes. We hypothesized that KCNJ11 mutations could pre...

Abstract A young female patient, diagnosed with diabetes mellitus at the age of 28 years old in 2009, carries KCNJ11 R136C by whole exome sequencing and her daughter doesn’t carry this mutation. Bioinformatics software predicted that 136th amino acid is highly conservative mutation deleterious. can result change channel port structure K ATP channel. So she was as -MODY.

In the absence of specific metabolic disorders, predictors of response to ketogenic dietary therapies (KDT) are unknown. We aimed to determine whether variants in established candidate genes KCNJ11 and BAD influence response to KDT. We sequenced KCNJ11 and BAD in individuals without previously-known glucose transporter type 1 deficiency syndrome or other metabolic disorders, who received KDT fo...

AIMS Mutations in the KCNJ11 gene, which encodes the Kir6.2 subunit of the pancreatic KATP channel, cause neonatal diabetes. KCNJ11 is also expressed in the brain, and ~ 20% of those affected have neurological features, which may include features suggestive of psychiatric disorder. No previous studies have systematically characterized the psychiatric morbidity in people with KCNJ11 neonatal dia...

H eterozygous activating mutations in the KCNJ11 gene are a common cause of permanent neonatal diabetes (PNDM) (1,2). In contrast to the autoimmune type 1 diabetes, patients with KCNJ11 mutations do not have serological markers of autoimmune -cell destruction at disease onset (1,3–5). In such patients, hyperglycemia does not result from insulin-secreting cell destruction but rather from impaire...

Permanent neonatal diabetes mellitus refers to diabetes that occurs before the age of 6 months and persists through life. It is a rare disorder affecting one in 0.2-0.5 million live births. Mutations in the gene KCNJ11, encoding the subunit Kir6.2, and ABCC8, encoding SUR1 of the ATP-sensitive potassium (KATP) channel, are the most common causes of permanent neonatal diabetes mellitus. Sulfonyl...

Permanent neonatal diabetes mellitus (PNDM) is a rare type of diabetes and KCNJ11 gene activating mutation is one of its prevalent causes. We introduced a 4-month-old male infant with poor feeding, restlessness, tachypnea, hyperglycemia, metabolic acidosis, and ketonemia. He was discharged with insulin and after 2 months, KCNJ11 gene mutation was found and treatment was switched from subcutaneo...

The most common monogenic cause of neonatal diabetes is mutation in KCNJ11, which encodes a potassium channel in pancreatic beta cells. Some mutations in this gene, including Q52R, have been described in association with neurological deficits, but never with hepatic involvement. We report the second case of neonatal diabetes in a patient with a KCNJ11/Q52R mutation. This patient's clinical cour...
