Genotype
MGI:3583952

• Allelic Composition: Hmga1^tm1Brun/Hmga1⁺
• Genetic Background: Not Specified

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

homeostasis/metabolism

decreased insulin secretion ( J:99652 )

• plasma insulin is also decreased after glucose challenge with a striking effect on acute first-phase insulin secretion

decreased circulating insulin level ( J:99652 )

• plasma insulin levels but not glucose levels are significantly reduced

impaired glucose tolerance ( J:99652 )

• glucose intolerance is 71% impaired glucose tolerance and 28% diabetes

increased insulin sensitivity ( J:99652 )

• increased insulin sensitivity is seen in the skeletal muscle and fat

insulin resistance ( J:99652 )

• insulin resistance is seen in the liver as seen by increased glucose production under hyperinsulinemic conditions

endocrine/exocrine glands

decreased insulin secretion ( J:99652 )

• plasma insulin is also decreased after glucose challenge with a striking effect on acute first-phase insulin secretion
