About Autosomal recessive hyperinsulinism due to Kir6.2 deficiency
What is Autosomal recessive hyperinsulinism due to Kir6.2 deficiency?
Autosomal recessive hyperinsulinism due to Kir6.2 deficiency is a rare genetic disorder caused by mutations in the KCNJ11 gene, which encodes the Kir6.2 protein. This disorder is characterized by excessive insulin production, resulting in hypoglycemia (low blood sugar). Symptoms of this disorder can include seizures, developmental delay, and failure to thrive. Treatment typically involves a combination of medications and dietary modifications.
What are the symptoms of Autosomal recessive hyperinsulinism due to Kir6.2 deficiency?
The symptoms of Autosomal recessive hyperinsulinism due to Kir6.2 deficiency include:
-Hypoglycemia (low blood sugar)
-Poor feeding
-Irritability
-Sweating
-Tremors
-Seizures
-Lethargy
-Coma
-Developmental delay
-Failure to thrive
-Weight loss
-Dehydration
-Hypotonia (low muscle tone)
-Hypothermia (low body temperature)
What are the causes of Autosomal recessive hyperinsulinism due to Kir6.2 deficiency?
Autosomal recessive hyperinsulinism due to Kir6.2 deficiency is caused by mutations in the KCNJ11 gene, which encodes the Kir6.2 subunit of the ATP-sensitive potassium channel. Mutations in this gene lead to a decrease in the activity of the channel, resulting in an increase in insulin secretion from the pancreas.
What are the treatments for Autosomal recessive hyperinsulinism due to Kir6.2 deficiency?
1. Dietary therapy: Dietary therapy is the mainstay of treatment for autosomal recessive hyperinsulinism due to Kir6.2 deficiency. This involves a low-carbohydrate, high-fat diet, which helps to reduce the amount of insulin released by the pancreas.
2. Medication: Medications such as diazoxide and octreotide can be used to reduce the amount of insulin released by the pancreas.
3. Surgery: Surgery may be recommended in some cases to remove part of the pancreas. This can help to reduce the amount of insulin released by the pancreas.
4. Glucose monitoring: Regular monitoring of blood glucose levels is important to ensure that the treatment is effective.
What are the risk factors for Autosomal recessive hyperinsulinism due to Kir6.2 deficiency?
1. Family history of Autosomal recessive hyperinsulinism due to Kir6.2 deficiency
2. Being of Ashkenazi Jewish descent
3. Having a mutation in the KCNJ11 gene
4. Having a mutation in the ABCC8 gene
5. Having a mutation in the SLC16A1 gene
6. Having a mutation in the GCK gene
7. Having a mutation in the HNF1A gene
8. Having a mutation in the HNF4A gene
9. Having a mutation in the HNF1B gene
10. Having a mutation in the UCP2 gene
Is there a cure/medications for Autosomal recessive hyperinsulinism due to Kir6.2 deficiency?
Yes, there is a cure for Autosomal recessive hyperinsulinism due to Kir6.2 deficiency. The treatment involves a low-glucose diet, medications such as diazoxide and octreotide, and surgery to remove the affected part of the pancreas. In some cases, a liver transplant may be necessary.
