  1. 1.Hunter Syndrome

    Hunter syndrome is a rare genetic disorder, which is part of a family of diseases called lysosomal storage disorders. People with Hunter syndrome lack a protein that helps break down certain molecules. If these molecules build up within the body, they can cause issues with the heart, bones, and the nervous system, resulting in cognitive decline.

    Most improvements occur in the first 12-18 months of treatment, but this genetic disorder unfortunately does not yet have a cure.

    Rarity:
    Rare
    Top Symptoms:
    shortness of breath, joint stiffness, hearing loss, disproportionately large head, developmental delay
    Urgency:
    Primary care doctor
  2. 2.Digeorge Syndrome

    DiGeorge syndrome (22q11.2 deletion syndrome), a disorder caused by a defect in chromosome 22, results in the poor development of several body systems. Medical problems commonly associated with DiGeorge syndrome include heart defects, poor immune system function, a cleft palate, complications related to low levels of calcium in the blood and behavioral disorders.

    Genetic disorders of this type are irreversible, but many symptoms can be effectively managed with treatment.

  3. 3.Left Ventricular Noncompaction

    In left ventricular noncompaction (LVNC) the lower left chamber of the heart called the left ventricle, contains bundles or pieces of muscle that extend into the chamber and develops abnormally in the uterus. As a result, the heart becomes smooth and solid instead of spongy.

    This condition is considered irreversible, but detection and treatment options have advanced in recent years. In some cases, heart transplantation is an option.
