What is Rapid-Onset Obesity with Hypothalamic Dysfunction, Hypoventilation, and Autonomic Dysregulation (ROHHAD)?
Rapid-Onset Obesity with Hypothalamic Dysfunction, Hypoventilation, and Autonomic Dysregulation (ROHHAD) is a rare disorder of respiratory control and autonomic nervous system (ANS) regulation, with endocrine system abnormalities. ROHHAD presents after 1.5 years of age, in otherwise healthy children. The rapid-onset weight gain (often 30 pounds in 6-12 months) is typically the herald of the disease and the harbinger of the later features of the ROHHAD phenotype. The acronym ROHHAD describes the typical sequence of symptoms experienced by most children with ROHHAD, in the order of their appearance. The clinical features of ROHHAD seem to “unfold” with advancing age in each child.

Raynaud's Phenomenon

Awareness Ribbon Color:

Purple - Red - White Ribbon for Raynaud's Phenomenon

What is Raynaud's Phenomenon (RP)?
Raynaud’s Phenomenon (RP) results when there is a decrease in blood flow to the fingers and toes when someone is exposed to cold weather or stress. The fingers or toes typically change colors including white, blue and red. This can be associated with a “pins and needles” sensation or discomfort. These symptoms occur intermittently, and are known as “episodes” or “attacks”, and tend to resolve on their own.

There are two types of Raynaud’s Phenomenon, which are referred to as “primary” and “secondary”. Primary Raynaud’s typically affects women under the age of 30. While symptoms can be uncomfortable, there is no danger of damage to the body. Primary Raynaud’s occurs in people who do not have another rheumatic disease. Secondary Raynaud’s is “secondary” to another condition. These conditions are numerous and can include several autoimmune conditions. The most common rheumatic diseases associated with Raynaud’s include Scleroderma and Lupus, but can include others such as Rheumatoid Arthritis, Inflammatory Myositis, and Sjögren’s Syndrome.

Reactive Arthritis is also known as:
• Fiessinger-Leroy Disease
• Reiter's Syndrome

What is Reactive Arthritis?
Reactive Arthritis is a general term for a form of joint inflammation (arthritis) that develops as a "reaction" to an infection in another area of the body. In reactive arthritis, the large joints of the lower limbs and the sacroiliac joints are most often affected. Two other common symptoms of reactive arthritis are inflammation of the urinary tract and inflammation of the membrane that lines the eyelids. These three characteristic symptoms may occur separately, all at once or not at all. Reactive arthritis belongs to a group of related disorders known as the Spondyloarthritidies. These disorders are linked by the association of similar symptoms and a specific genetic marker called HLA-B27.

What is Recurrent Cancer?
If cancer is found after treatment, and after a period of time when the cancer could not be detected, it is called a cancer recurrence. The recurrent cancer might come back in the same place it first started, or it might come back somewhere else in the body. When cancer spreads to a new part of the body, it is still named after the part of the body where it started. For instance, prostate cancer might come back in the area of the prostate gland (even if the gland was removed), or it might come back in the bones. In either case it is a prostate cancer recurrence. It may be called recurrent prostate cancer. The cancer in the bones is treated like prostate cancer.

What is Recurrent Respiratory Papillomatosis (RRP)?
Recurrent Respiratory Papillomatosis (RRP) is a rare disorder characterized by the development of small, wart-like growths (papillomas) in the respiratory tract. Papillomas can develop anywhere along the respiratory tract, but most often affect the larynx and the vocal cords (laryngeal papillomatosis). Less often, the disorder affects the area within the mouth (oral cavity), trachea and bronchi. Only in rare cases do these growths spread to affect the lungs. Papillomas are noncancerous (benign), but in extremely rare cases can undergo cancerous (malignant) transformation. Although benign, papillomas can cause severe, even life-threatening airway obstruction and respiratory complications. In RRP, papillomas have a tendency to grow back after they have been removed.

What is Retinoblastoma?
Retinoblastoma is an extremely rare malignant tumor that develops in the nerve-rich layers that line the back of the eyes (retina). Retinoblastoma is most commonly diagnosed in children under the age of three. The most typical finding associated with retinoblastoma is the reflection of light off a tumor behind the lens of the eye, which causes the pupil to appear white, the so-called “cat’s eye reflex”. In addition, the eyes may be misaligned so that they appear crossed. In some affected children, the eye(s) may become red and/or painful. The presence of a retinoblastoma may cause glaucoma, a condition marked by a rise in the pressure within the eyeball that prevents the normal drainage of fluid from the eye and potentially causes characteristic damage to the optic nerve. Retinoblastoma may affect one eye or both eyes. Retinoblastomas occur in two forms, heritable and non-heritable. Bilateral forms are heritable and usually diagnosed at a younger age. In most affected children, retinoblastoma is non-heritable; it occurs spontaneously for no apparent reason.

Retinopathy of Prematurity is also known as:
• Retrolental Fibroplasia (obsolete)
• ROP

What is Retinopathy of Prematurity (ROP)?
Retinopathy of prematurity (ROP) is a potentially blinding disease affecting the retinas in premature infants. In infants born prematurely, the blood vessels that supply the retinas are not yet completely developed. Although blood vessel growth continues after birth, these vessels may develop in an abnormal, disorganized pattern, known as ROP. In some affected infants, the changes associated with ROP spontaneously subside. However, in others, ROP may lead to bleeding, scarring of the retina, retinal detachment and visual loss.

What is Retinoschisis?
Retinoschisis means splitting of the eye's retina into two layers. There are two forms of this disorder. The most common is an acquired form that affects both men and women. It usually occurs in middle age or beyond, although it can occur earlier, and it is sometimes known as senile retinoschisis. The other form is present at birth (congenital) and affects mostly boys and young men. It is known as juvenile, X-linked retinoschisis. The disorder is characterized by a slow, progressive loss of parts of the field of vision corresponding to the areas of the retina that have become split. Either form may be associated with the development of saclike blister.

What is Rocky Mountain Spotted Fever (RMSF)?
Rocky Mountain spotted fever (RMSF) is an infectious disease that belongs to a group of diseases known as the spotted fever group rickettsioses. It is caused by infection with the bacterium Rickettsia rickettsii (R. rickettsii), which is usually transmitted by a tick bite. When introduced into the body, the bacterium spreads by the bloodstream or lymphatic vessels and multiplies within and damages certain cells lining the inside of small blood vessels as well as vascular smooth muscle cells.

Approximately two to 14 days after initial infection, early symptoms may include a high fever, severe headaches, muscle pain, nausea, vomiting, loss of appetite, or abdominal pain. In addition, in most individuals with RMSF, a distinctive rash develops about three to five days after fever onset. The rash typically initially consists of small, flat pinkish spots that eventually become raised and darker. The lesions usually develop "pin-point" reddish spots due to localized bleeding and may merge to form larger hemorrhagic patches.

RYR-1-Related Diseases is also known as:
• RYR-1 Myopathy
• RYR-1 Muscle Disease

What is RYR-1-Related Diseases?
RYR-1-Related Diseases are conditions caused by changes in the RYR-1 gene. RYR-1 mutations are typically associated with core myopathies and are the most common overall cause of congenital myopathy. A myopathy can cause “static” or “dynamic” symptoms. “Static” symptoms are present at all times. “Dynamic” symptoms are transient based on certain triggers or precipitants. Individuals with RYR-1-related diseases can experience “static” symptoms, “dynamic” symptoms, or a combination of both.
