Abstract:
Adrenal hypoplasia congenita (AHC) causes primary adrenal insufficiency due to the failure of development of the adrenal cortex. Clinical and pedigree data indicate that the condition is genetically heterogeneous. The predominant adrenal hypoplasia congenita locus, however, is the NR0B1 gene, at Xp21, encoding the protein DAX1. In this article, we present a compendium of published NR0B1 mutations and polymorphisms, and discuss them in the contexts of known biology and clinical applicability. The recent descriptions of patients with primary adrenal insufficiency due to mutations of NR5A1, which encodes SF1, are also discussed.

There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...
Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...

Smooth Endoplasmic Reticulum
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.
