Insights

DiGeorge anomaly and renal agenesis co-occur, particularly in infants of mothers with insulin-dependent diabetes mellitus (IDDM). This suggests a potential developmental association linked to maternal diabetes.

Area of Science:

  • Developmental biology
  • Medical genetics
  • Pediatric medicine

Background:

  • DiGeorge anomaly is a condition affecting development of the thymus, parathyroid glands, and heart.
  • Bilateral renal agenesis is a congenital absence of both kidneys.
  • Insulin-dependent diabetes mellitus (IDDM) in mothers is a known risk factor for certain birth defects.

Observation:

  • Two cases of DiGeorge anomaly with bilateral renal agenesis are presented.
  • One infant also had hemivertebrae and a mother with IDDM.
  • A literature review identified two additional cases of this combination, both in infants of mothers with IDDM.

Findings:

  • The co-occurrence of DiGeorge anomaly and bilateral renal agenesis is observed.
  • The association appears more frequent in infants born to mothers with insulin-dependent diabetes mellitus.
  • This suggests a potential shared etiology or developmental field defect.

Implications:

  • The findings suggest a specific association between DiGeorge anomaly, renal agenesis, and maternal IDDM.
  • Further research is warranted to elucidate the underlying mechanisms.
  • This association may inform genetic counseling and prenatal risk assessment for affected families.

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
Diabetes Mellitus: Introduction01:26

Diabetes Mellitus: Introduction

Diabetes mellitus consists of chronic metabolic disorders characterized by persistent hyperglycemia. This elevated blood glucose results from defects in insulin secretion, impaired insulin action, or both. Insulin, produced by pancreatic β-cells, is essential for maintaining glucose homeostasis by facilitating cellular glucose uptake for energy or storage. Disruptions in insulin production or function lead to glucose accumulation in the bloodstream, causing the clinical features and long-term...

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Diabetic Nephropathy

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
