user: What is (are) Chromosome 19p deletion ?

assistant: Chromosome 19p deletion is a chromosome abnormality that occurs when there is a missing (deleted) copy of genetic material on the short arm (p) of chromosome 19. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 19p deletion include developmental delay, intellectual disability, behavioral problems and distinctive facial features. Chromosome testing of both parents can provide more information on whether or not the deletion was inherited. In most cases, parents do not have any chromosomal anomaly. However, sometimes one parent is found to have a balanced translocation, where a piece of a chromosome has broken off and attached to another one with no gain or loss of genetic material. The balanced translocation normally does not cause any signs or symptoms, but it increases the risk for having an affected child with a chromosomal anomaly like a deletion. Treatment is based on the signs and symptoms present in each person. This page is meant to provide general information about 19p deletions. You can contact GARD if you have questions about a specific deletion on chromosome 19. To learn more about chromosomal anomalies please visit our GARD webpage on FAQs about Chromosome Disorders.
user: What is (are) Spinocerebellar ataxia 2 ?

assistant: Spinocerebellar ataxia 2 (SCA2) is a progressive disorder that causes symptoms including uncoordinated movement (ataxia), speech and swallowing difficulties, muscle wasting, slow eye movement, and sometimes dementia. Signs and symptoms usually begin in mid-adulthood but can appear any time from childhood to late-adulthood. SCA2 is caused by mutations in the ATXN2 gene and is inherited in an autosomal dominant manner.
user: What are the symptoms of Spinocerebellar ataxia 2 ?

assistant: What are the signs and symptoms of Spinocerebellar ataxia 2? Early symptoms of spinocerebellar ataxia may include uncoordinated movement (ataxia) and leg cramps. Other symptoms may include tremor; decreased muscle tone; poor tendon reflexes; abnormal eye movements; dementia; dystonia and/or chorea; muscle twitches; nerve irritation and swelling (polyneuropathy); leg weakness; difficulty swallowing; bladder dysfunction; and parkinsonism. The Human Phenotype Ontology provides the following list of signs and symptoms for Spinocerebellar ataxia 2. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Autosomal dominant inheritance - Bradykinesia - Dementia - Dilated fourth ventricle - Distal amyotrophy - Dysarthria - Dysdiadochokinesis - Dysmetria - Dysmetric saccades - Dysphagia - Fasciculations - Gaze-evoked nystagmus - Genetic anticipation - Hyporeflexia - Impaired horizontal smooth pursuit - Limb ataxia - Muscular hypotonia - Myoclonus - Oculomotor apraxia - Olivopontocerebellar atrophy - Ophthalmoplegia - Postural instability - Postural tremor - Progressive cerebellar ataxia - Rigidity - Rod-cone dystrophy - Slow saccadic eye movements - Spasticity - Spinocerebellar tract degeneration - Urinary bladder sphincter dysfunction - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
user: Is Spinocerebellar ataxia 2 inherited ?

assistant: How is spinocerebellar ataxia 2 inherited? Spinocerebellar ataxia 2 (SCA2) is inherited in an autosomal dominant manner. This means that having one changed (mutated) copy of ATXN2 (the responsible gene) in each cell is enough to cause signs and symptoms of the condition. The ATXN2 gene mutations that cause SCA2 involve a DNA sequence called a 'CAG trinucleotide repeat.' It is made up of a series of three DNA building blocks (CAG stands for cytosine, adenine, and guanine) that appear multiple times in a row. The CAG sequence is normally repeated about 22 times in the gene, but it can be repeated up to 31 times without causing health problems. SCA2 develops in people who have 32 or more CAG repeats in the ATXN2 gene. In most cases, an affected person inherits the mutated gene (with too many repeats) from an affected parent. However, in some cases, an affected person does not have an affected parent. People with an increased number of CAG repeats who don't develop SCA2 are still at risk of having children who will develop the disorder. This is because as the gene is passed down from parent to child, the number of CAG repeats often increases. In general, the more repeats a person has, the earlier symptoms begin. This phenomenon is called anticipation. People with 32 or 33 repeats tend to develop symptoms in late adulthood, while people with more than 45 repeats often have symptoms by their teens.  For some reason, the number of repeats tend to increase more when the gene is inherited from a person's father than when inherited from a person's mother. Each child of an affected person has a 50% chance of inheriting the CAG repeat expansion.
user: How to diagnose Spinocerebellar ataxia 2 ?

assistant: Is genetic testing available for spinocerebellar ataxia 2? Yes. Molecular genetic testing (analysis of DNA) is needed for a diagnosis of spinocerebellar ataxia 2 (SCA2). This testing detects abnormal CAG trinucleotide repeat expansions in the ATXN2 gene. Affected people (or people who will later develop symptoms of SCA2) have a copy of the ATXN2 gene that has 33 or more CAG repeats. This testing detects nearly 100% of cases of SCA2. The Genetic Testing Registry (GTR) provides information about the labs that offer genetic testing for SCA2. The intended audience for the GTR is health care providers and researchers. Therefore, patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.
user: What are the treatments for Spinocerebellar ataxia 2 ?

assistant: How might spinocerebellar ataxia 2 be treated? Treatment of spinocerebellar ataxia 2 (SCA2) is supportive and aims to help the affected person maintain their independence and avoid injury. It is recommended that people with SCA2 remain physically active, maintain a healthy weight, use adaptive equipment as needed, and avoid alcohol and medications that affect cerebellar function. Adaptive equipment may include canes or other devices to help with walking and mobility. People with SCA2 may develop difficulty speaking and may need to use computerized devices or writing pads to help with communication. Levodopa may be prescribed to help with some of the movement problems (e.g., rigidity and tremor), and magnesium may improve muscle cramping.
user: What is (are) 16q24.3 microdeletion syndrome ?

assistant: 16q24.3 microdeletion syndrome is a chromosome abnormality that can affect many parts of the body. People with this condition are missing a small piece (deletion) of chromosome 16 at a location designated q24.3. Signs and symptoms may include developmental delay, characteristic facial features, seizures and autism spectrum disorder. Chromosome testing of both parents can provide more information on whether or not the microdeletion was inherited. In most cases, parents do not have any chromosomal anomaly. However, sometimes one parent has a balanced translocation where a piece of a chromosome has broken off and attached to another one with no gain or loss of genetic material. The balanced translocation normally does not cause any signs or symptoms, but it increases the risk for having an affected child with a chromosomal anomaly like a microdeletion. Treatment is based on the signs and symptoms present in each person. To learn more about chromosomal anomalies in general, please visit our GARD webpage on Chromosome Disorders.

user: What is (are) Beta ketothiolase deficiency ?

assistant: Beta-ketothiolase deficiency is an inherited disorder in which the body cannot effectively process a protein building block (amino acid) called isoleucine. This condition also impairs the body's ability to process ketones, which are molecules produced during the breakdown of fats. Signs and symptoms typically appear between the ages of 6 months and 24 months. Affected children experience episodes of vomiting, dehydration, difficulty breathing, extreme tiredness (lethargy), and occasionally seizures. These episodes, which are called ketoacidotic attacks, sometimes lead to coma. Ketoacidotic attacks are frequently triggered by infections, periods without food (fasting), or increased intake of protein-rich foods. This condition is inherited in an autosomal recessive fashion and is caused by mutations in the ACAT1 gene.

user: What is (are) Phacomatosis pigmentovascularis ?

assistant: Phacomatosis pigmentovascularis (PPV) is a skin and blood vessel disorder that is present from birth. Common signs and symptoms include port wine stain and pigmentary lesions, such as melanocytic nevi or epidermal nevi. A variety of classification systems have been proposed for PPV, largely depending on what type of pigmentary lesion is present. Around half of individuals with PPV have systemic disease, meaning that body systems other than the skin are affected. Systemic symptoms can vary greatly from person to person. PPV is not inherited, but is thought to be caused by a genetic phenomenon called twin spotting.
user: What are the symptoms of Phacomatosis pigmentovascularis ?

assistant: What are the signs and symptoms of phacomatosis pigmentovascularis? Characteristic signs and symptoms of phacomatosis pigmentovascularis (PPV), include port wine stain and pigmentary lesions. The port wine stain and pigmentary lesions are often extensive and can affect several areas of the body, including the face. Examples of associated pigmentary lesions, include: Melanocytic nevi  Epidermal nevi   In addition to the port wine stain and pigmentary lesions, other skin lesions are not uncommon, such as: Nevus anemicus  Cafe-au-lait spots Mongolian spots Nevus of Ota Nevus of Ito Nevus spilus Around half of people with PPV have systemic involvement (i.e., other body systems are affected). Eye conditions such as ocular melanosis (also called ocular melanocytosis) is common. Ocular melanosis refers to a blue-gray pigmentation in the 'white of the eye' or sclerae. This condition often occurs along with nevus of Ota and may affect one or both eyes. The complications of nevus of Ota are glaucoma and melanoma, as a result people with nevus of Ota require careful examination and follow-up by an opthamologist. Other eye conditions reported in PPV include iris hamartomas, iris mammillations, and iris nodules. Some individuals with PPV also have Sturge-Weber syndrome or Klippel-Trenaunay syndrome. Signs and symptoms of Sturge-Weber syndrome include a large port-wine stain facial birthmark, blood vessel abnormalities in the brain called leptomeningeal angiomas, as well as glaucoma, seizures, muscle weakness, paralysis, developmental delay, and intellectual disability. Klippel-Trenaunay syndrome is characterized by a port-wine stain, abnormal overgrowth of soft tissues and bones, and vein malformations. You can learn more about Sturge-Weber syndrome on our Web site at the following link: http://rarediseases.info.nih.gov/GARD/Condition/7706/Sturge_Weber_syndrome.aspx You can learn more about Klippel-Trenaunay syndrome on the Genetic Home Reference Web site at the following link: http://ghr.nlm.nih.gov/condition/klippel-trenaunay-syndrome  A variety of other symptoms have been reported in individual cases of PPV (e.g., primary lymphedema, renal angiomas, moyamoya disease, scoliosis, malignant colonic polyposis, hypoplastic larynx, multiple granular cell tumors, and selective IgA deficiency). Conditions associated with PPV can vary greatly from person to person and can be difficult to predict.
user: What causes Phacomatosis pigmentovascularis ?

assistant: What causes phacomatosis pigmentovascularis? Phacomatosis pigmentovascularis (PPV) is thought to occur as a result of a change in the arrangement of a small piece of genetic material in a developing embryo. Because of this change some of the baby's body cells carry two copies of recessive gene mutations while the majority of his or her body cells carry only one. Having two copies of the recessive gene mutations result in a diseased cell (and symptoms of PPV). This phenomenon is called twin spotting. PPV occurs by chance, it is not inherited, and affects only a subset of the body's cells. As a result risk to future offspring is very small.
user: How to diagnose Phacomatosis pigmentovascularis ?

assistant: How might phacomatosis pigmentovascularis be diagnosed? Diagnosis of phacomatosis pigmentovascularis is based primarily on physical evaluation and appearence of the skin lesions.
user: What are the treatments for Phacomatosis pigmentovascularis ?

assistant: How might phacomatosis pigmentovascularis be treated? If phacomatosis pigmentovascularis (PPV) is not associated with systemic complications (e.g., Sturge-Weber syndrome, Klippel-Trenaunay syndrome, eye conditions) it requires no treatment, however pulsed dye laser may improve the appearance of port wine stains and Q-switched laser the appearance of pigmentary nevus. Medical treatment of PPV with systemic complications requires individualized plans and often assistance from a team of specialists (e.g., opthamologist, neurologist, and vascular specialist).
user: What is (are) Mucoepidermoid carcinoma ?

assistant: Mucoepidermoid carcinoma is a type of cancer of the salivary glands.  Salivary gland cancer is diagnosed in 2-3 individuals per 100,000 people each year, and 30-35% of these are mucoepidermoid carcinomas.   Mucoepidermoid carcinoma develops when a cell randomly acquires changes (mutations) in genes that regulate how the cell divides such that it begins to grow quickly, forming a cluster of cells (a mass or lump).  The earliest signs of a mucoepidermoid carcinoma may include a lump in the face, neck, or mouth; numbness, weakness, or pain in part of the face; or difficulty swallowing.  Treatment often begins with surgery to remove the entire tumor.  In some cases, radiation therapy and/or chemotherapy may be used after surgery to ensure that no cancer cells remain in the body.
user: What is (are) Cerulean cataract ?

assistant: Cerulean cataracts are opaque areas that develop in the lens of the eye that often have a bluish or whitish color. They may be present at birth or develop in very early childhood, but may not be diagnosed until adulthood. They are usually bilateral and progressive. Infants can be asymptomatic, but may also be visually impaired from birth and develop nystagmus and amblyopia. In adulthood, the cataracts may progress, making lens removal necessary. Cerulean cataracts may be caused by mutations in several genes, including the CRYBB2, CRYGD, and MAF genes, and are inherited in an autosomal dominant manner. No treatment is known to prevent cerulean cataracts, but frequent evaluations and cataract surgery are typically required to prevent amblyopia as the opacities progress.
