Discover the importance of diagnosing childhood-onset Wolff-Parkinson-White syndrome, the role of genetic testing, and effective management strategies for patients.

IgA, IgD, IgE, IgG and IgM levels shift with age, infection and immune disease; blood tests measure them and DNA testing looks for causative mutations.

Germline TP53 mutations and phosphodiesterase gene variants feature in pediatric ACC, where abdominal pain, rapid growth or early puberty can be the first signs.

Discover the role of aldosterone-to-renin ratio in diagnosing primary aldosteronism, the impact of various factors on ARR, and the benefits of genetic testing.

Airway inflammation plus soft growths in the nasal lining bring congestion, wheezing and reduced smell; genetic findings can shape treatment and track response.

Mutations in the α-tocopherol transfer protein gene leave vitamin E levels low, producing ataxia that mimics Friedreich's ataxia until testing tells them apart.

Sialidosis type 1 and neuronal ceroid lipofuscinosis with a CLN6 mutation are two disorders behind this symptom cluster, which genetic testing can tell apart.

Electrical activity is absent in the atria, bringing irregular heartbeats and fainting; EMD and LMNA testing identifies the digenic cause and relatives' risk.
