Autosomal Dominant Hypocalcemia

Autosomal Dominant Hypocalcemia (ADH) is a genetic condition that leads to low levels of calcium in the blood. This article aims to explain the condition in simple terms, covering its causes, symptoms, diagnostic methods, treatments, and much more.

ADH is a genetic disorder passed down through families. In this condition, the body doesn’t properly manage calcium levels, leading to lower than normal calcium in the blood. Calcium is crucial for many bodily functions, including bone health, nerve function, and muscle contractions.

Pathophysiology

Structure

Calcium is primarily stored in bones, with smaller amounts in the blood and cells. The parathyroid glands, located near the thyroid gland in the neck, play a key role in regulating calcium levels. They produce parathyroid hormone (PTH), which helps control calcium levels by influencing how much calcium the bones release, how much the kidneys excrete, and how much the intestines absorb from food.

Blood

In ADH, mutations in specific genes affect how the body handles calcium. This leads to decreased blood calcium levels. Low calcium levels can trigger various symptoms, including muscle cramps, tingling sensations, and more severe complications if not managed properly.

Nerve Supply

Calcium is essential for nerve function. It helps transmit signals between nerve cells. When calcium levels are low, it can disrupt these signals, leading to neurological symptoms like tingling and muscle spasms.

Types of Autosomal Dominant Hypocalcemia

1. ADH Type 1: Caused by mutations in the CaSR gene.
2. ADH Type 2: Caused by mutations in the GNA11 gene.
3. ADH Type 3: Linked to mutations in the AP2S1 gene.

Causes of Autosomal Dominant Hypocalcemia

Here are 20 potential causes of ADH:
