Insights

This study details a rare case of Multiple Endocrine Neoplasia (MEN) type 2A in an Iranian family, identifying a specific RET gene mutation. The findings contribute to understanding MEN 2A

Area of Science:

  • Endocrinology
  • Genetics
  • Oncology

Background:

  • Multiple Endocrine Neoplasia (MEN) type 2A is an inherited disorder.
  • It is caused by activating mutations in the RET protooncogene.
  • MEN 2A is associated with medullary thyroid carcinoma, pheochromocytoma, and hyperparathyroidism.

Observation:

  • Limited data exists on MEN type 2 in the Middle East.
  • This paper presents clinical and genetic findings of an Iranian patient and her family.
  • The patient, a 49-year-old woman, had hypertension due to bilateral pheochromocytoma and a history of medullary thyroid carcinoma.

Findings:

  • RET gene analysis revealed a C634R mutation in codon 11.
  • Three polymorphisms (G691S, S836S, S904S) were identified in codons 11, 14, and 15.
  • These genetic variations may influence the clinical presentation of MEN 2A.

Implications:

  • This study addresses the paucity of information on MEN type 2 in the Middle East.
  • It provides insights into the clinical and cytogenetic characteristics of the disease in the region.
  • The findings can aid in diagnosis and management of MEN 2A in Iranian populations.

Cushing Syndrome II: Pathophysiology

Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features...

Type II Diabetes II: Pathophysiology

PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.

Type II Diabetes I: Introduction01:26

Type II Diabetes I: Introduction

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH...
