Learn about the role that genetics plays in many heart conditions that afflict children.
Learn about the types of heart conditions that arise in children. Congenital heart defects and heart rhythm problems are among the conditions discussed.
Learn about heart tumours in children, and how they are diagnosed. Both the most common types of benign and malignant tumours are discussed.
Learn about heart-related syndromes. A syndrome is a medical term for a collection of signs and symptoms that generally stem from a single cause.
Noonan syndrome is a genetic condition. Learn about the symptoms and diagnosis of Noonan syndrome and the heart conditions associated with the condition.
Learn about the genetic neuromuscular disorder called Friedreich ataxia (FRDA).
Congenital myasthenic syndrome (CMS) is caused by genetic mutations that cause problems with nerve-to-muscle communication leading to muscle weakness and fatigue.
Learn about facioscapulohumeral muscular dystrophy (FSHD) disease, a genetic condition that leads to progressive muscle weakness and loss of muscle bulk mostly affecting the facial, shoulder and upper arm muscles.
Learn about hypoplastic left heart syndrome (HLHS). This condition involves the left side of the heart being underdeveloped, and is extremely serious.
An overview of the causes, symptoms and treatment of this blood disorder caused by a defect in the gene that controls the production of hemoglobin.
Myotonic dystrophy type 1 (DM1) disease is a genetic disorder that causes muscle stiffness, that over time causes the muscles to become weaker and smaller.
Learn about genetics and how genetics contribute to health and disease.
Spinal muscular atrophy (SMA) is a genetic disorder that causes muscle weakness and muscle atrophy (shrinking), and can affect a child’s ability to speak, walk, and breathe.
Thrombophilia is a blood clotting that increases the risk of developing blood clots in the blood vessels. The second most common type of inherited thrombophilia is the prothrombin gene mutation.
There are many types of cancer, but there are some things that are similar in most cancers. Learn about cells, tumours and how cancer spreads.
Hereditary spherocytosis is a genetic condition. In most cases it is inherited from a parent. Learn how HS is inherited and what happens in a de novo mutation.
Learn how gene changes can cause acute lymphoblastic leukemia (ALL).
Macrophage activation syndrome (MAS) occurs when the immune system is overactivated and causes inflammation. Learn about the signs, causes and treatment of MAS.
Learn about different kinds of tachycardia (fast heart rate) and how tachycardia is treated.
Neurofibromatosis Type 1 (NF1) occurs because of a mutation to the NF1 gene. About half of cases are spontaneous mutations, while the other half are inherited from a parent to a child.
Learn about atrioventricular septal defects (AVSD) in children. This condition involves the lung overfilling with blood.
Primary ciliary dyskinesia (PCD) is a rare inherited disease that can cause recurring lung, ear and sinus infections. Find out how the condition is caused and treated and the long-term outlook for children with PCD.
Tuberous sclerosis complex (TSC) is a genetic condition. Learn what causes it, and how it is diagnosed and treated.
A teacher's guide to congenital heart defects. Learn what you can do to help and what to expect if one of your students has a congenital heart defect.
Learn about coarctation of the aorta, a condition that involves a narrowing of the major artery leading from the heart to the body, affecting blood pressure. Find out how this condition can impact your life now and in the future.
