What are the genetic changes related to Carpenter syndrome ? 
 Mutations in the RAB23 or MEGF8 gene cause Carpenter syndrome.  The RAB23 gene provides instructions for making a protein that is involved in a process called vesicle trafficking, which moves proteins and other molecules within cells in sac-like structures called vesicles. The Rab23 protein transports vesicles from the cell membrane to their proper location inside the cell. Vesicle trafficking is important for the transport of materials that are needed to trigger signaling during development. For example, the Rab23 protein regulates a developmental pathway called the hedgehog signaling pathway that is critical in cell growth (proliferation), cell specialization, and the normal shaping (patterning) of many parts of the body.  The MEGF8 gene provides instructions for making a protein whose function is unclear. Based on its structure, the Megf8 protein may be involved in cell processes such as sticking cells together (cell adhesion) and helping proteins interact with each other. Researchers also suspect that the Megf8 protein plays a role in normal body patterning.  Mutations in the RAB23 or MEGF8 gene lead to the production of proteins with little or no function. It is unclear how disruptions in protein function lead to the features of Carpenter syndrome, but it is likely that interference with normal body patterning plays a role. For reasons that are unknown, people with MEGF8 gene mutations are more likely to have dextrocardia and other organ positioning abnormalities and less severe craniosynostosis than individuals with RAB23 gene mutations.
Is Carpenter syndrome inherited ? 
 This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

What is (are) Potocki-Shaffer syndrome ? 
 Potocki-Shaffer syndrome is a disorder that affects development of the bones, nerve cells in the brain, and other tissues. Most people with this condition have multiple noncancerous (benign) bone tumors called osteochondromas. In rare instances, these tumors become cancerous. People with Potocki-Shaffer syndrome also have enlarged openings in the two bones that make up much of the top and sides of the skull (enlarged parietal foramina). These abnormal openings form extra "soft spots" on the head, in addition to the two that newborns normally have. Unlike the usual newborn soft spots, the enlarged parietal foramina remain open throughout life.  The signs and symptoms of Potocki-Shaffer syndrome vary widely. In addition to multiple osteochondromas and enlarged parietal foramina, affected individuals often have intellectual disability and delayed development of speech, motor skills (such as sitting and walking), and social skills. Many people with this condition have distinctive facial features, which can include a wide, short skull (brachycephaly); a prominent forehead; a narrow bridge of the nose; a shortened distance between the nose and upper lip (a short philtrum); and a downturned mouth. Less commonly, Potocki-Shaffer syndrome causes vision problems, additional skeletal abnormalities, and defects in the heart, kidneys, and urinary tract.
How many people are affected by Potocki-Shaffer syndrome ? 
 Potocki-Shaffer syndrome is a rare condition, although its prevalence is unknown. Fewer than 100 cases have been reported in the scientific literature.
What are the genetic changes related to Potocki-Shaffer syndrome ? 
 Potocki-Shaffer syndrome (also known as proximal 11p deletion syndrome) is caused by a deletion of genetic material from the short (p) arm of chromosome 11 at a position designated 11p11.2. The size of the deletion varies among affected individuals. Studies suggest that the full spectrum of features is caused by a deletion of at least 2.1 million DNA building blocks (base pairs), also written as 2.1 megabases (Mb). The loss of multiple genes within the deleted region causes the varied signs and symptoms of Potocki-Shaffer syndrome.  In particular, deletion of the EXT2, ALX4, and PHF21A genes are associated with several of the characteristic features of Potocki-Shaffer syndrome. Research shows that loss of the EXT2 gene is associated with the development of multiple osteochondromas in affected individuals. Deletion of another gene, ALX4, causes the enlarged parietal foramina found in people with this condition. In addition, loss of the PHF21A gene is the cause of intellectual disability and distinctive facial features in many people with the condition. The loss of additional genes in the deleted region likely contributes to the other features of Potocki-Shaffer syndrome.
Is Potocki-Shaffer syndrome inherited ? 
 Potocki-Shaffer syndrome follows an autosomal dominant inheritance pattern, which means a deletion of genetic material from one copy of chromosome 11 is sufficient to cause the disorder. In some cases, an affected person inherits the chromosome with a deleted segment from an affected parent. More commonly, the condition results from a deletion that occurs during the formation of reproductive cells (eggs and sperm) in a parent or in early fetal development. These cases occur in people with no history of the disorder in their family.

What is (are) osteogenesis imperfecta ? 
 Osteogenesis imperfecta (OI) is a group of genetic disorders that mainly affect the bones. The term "osteogenesis imperfecta" means imperfect bone formation. People with this condition have bones that break easily, often from mild trauma or with no apparent cause. Multiple fractures are common, and in severe cases, can occur even before birth. Milder cases may involve only a few fractures over a person's lifetime.  There are at least eight recognized forms of osteogenesis imperfecta, designated type I through type VIII. The types can be distinguished by their signs and symptoms, although their characteristic features overlap. Type I is the mildest form of osteogenesis imperfecta and type II is the most severe; other types of this condition have signs and symptoms that fall somewhere between these two extremes. Increasingly, genetic factors are used to define the different forms of osteogenesis imperfecta.  The milder forms of osteogenesis imperfecta, including type I, are characterized by bone fractures during childhood and adolescence that often result from minor trauma. Fractures occur less frequently in adulthood. People with mild forms of the condition typically have a blue or grey tint to the part of the eye that is usually white (the sclera), and may develop hearing loss in adulthood. Affected individuals are usually of normal or near normal height.  Other types of osteogenesis imperfecta are more severe, causing frequent bone fractures that may begin before birth and result from little or no trauma. Additional features of these conditions can include blue sclerae, short stature, hearing loss, respiratory problems, and a disorder of tooth development called dentinogenesis imperfecta. The most severe forms of osteogenesis imperfecta, particularly type II, can include an abnormally small, fragile rib cage and underdeveloped lungs. Infants with these abnormalities have life-threatening problems with breathing and often die shortly after birth.
How many people are affected by osteogenesis imperfecta ? 
 This condition affects an estimated 6 to 7 per 100,000 people worldwide. Types I and IV are the most common forms of osteogenesis imperfecta, affecting 4 to 5 per 100,000 people.
What are the genetic changes related to osteogenesis imperfecta ? 
 Mutations in the COL1A1, COL1A2, CRTAP, and P3H1 genes cause osteogenesis imperfecta.  Mutations in the COL1A1 and COL1A2 genes are responsible for more than 90 percent of all cases of osteogenesis imperfecta. These genes provide instructions for making proteins that are used to assemble type I collagen. This type of collagen is the most abundant protein in bone, skin, and other connective tissues that provide structure and strength to the body.  Most of the mutations that cause osteogenesis imperfecta type I occur in the COL1A1 gene. These genetic changes reduce the amount of type I collagen produced in the body, which causes bones to be brittle and to fracture easily. The mutations responsible for most cases of osteogenesis imperfecta types II, III, and IV occur in either the COL1A1 or COL1A2 gene. These mutations typically alter the structure of type I collagen molecules. A defect in the structure of type I collagen weakens connective tissues, particularly bone, resulting in the characteristic features of osteogenesis imperfecta.  Mutations in the CRTAP and P3H1 genes are responsible for rare, often severe cases of osteogenesis imperfecta. Cases caused by CRTAP mutations are usually classified as type VII; when P3H1 mutations underlie the condition, it is classified as type VIII. The proteins produced from these genes work together to process collagen into its mature form. Mutations in either gene disrupt the normal folding, assembly, and secretion of collagen molecules. These defects weaken connective tissues, leading to severe bone abnormalities and problems with growth.  In cases of osteogenesis imperfecta without identified mutations in one of the genes described above, the cause of the disorder is unknown. These cases include osteogenesis imperfecta types V and VI. Researchers are working to identify additional genes that may be responsible for these conditions.
Is osteogenesis imperfecta inherited ? 
 Most cases of osteogenesis imperfecta have an autosomal dominant pattern of inheritance, which means one copy of the altered gene in each cell is sufficient to cause the condition. Many people with type I or type IV osteogenesis imperfecta inherit a mutation from a parent who has the disorder. Most infants with more severe forms of osteogenesis imperfecta (such as type II and type III) have no history of the condition in their family. In these infants, the condition is caused by new (sporadic) mutations in the COL1A1 or COL1A2 gene.  Less commonly, osteogenesis imperfecta has an autosomal recessive pattern of inheritance. Autosomal recessive inheritance means two copies of the gene in each cell are altered. The parents of a child with an autosomal recessive disorder typically are not affected, but each carry one copy of the altered gene. Some cases of osteogenesis imperfecta type III are autosomal recessive; these cases usually result from mutations in genes other than COL1A1 and COL1A2. When osteogenesis imperfecta is caused by mutations in the CRTAP or P3H1 gene, the condition also has an autosomal recessive pattern of inheritance.

What is (are) lung cancer ? 
 Lung cancer is a disease in which certain cells in the lungs become abnormal and multiply uncontrollably to form a tumor. Lung cancer may or may not cause signs or symptoms in its early stages. Some people with lung cancer have chest pain, frequent coughing, breathing problems, trouble swallowing or speaking, blood in the mucus, loss of appetite and weight loss, fatigue, or swelling in the face or neck. Lung cancer occurs most often in adults in their sixties or seventies. Most people who develop lung cancer have a history of long-term tobacco smoking; however, the condition can occur in people who have never smoked.  Lung cancer is generally divided into two types, small cell lung cancer and non-small cell lung cancer, based on the size of the affected cells when viewed under a microscope. Non-small cell lung cancer accounts for 85 percent of lung cancer, while small cell lung cancer accounts for the remaining 15 percent.  Small cell lung cancer grows quickly and often spreads to other tissues (metastasizes), most commonly to the adrenal glands (small hormone-producing glands located on top of each kidney), liver, brain, and bones. In more than half of cases, the small cell lung cancer has spread beyond the lung at the time of diagnosis. After diagnosis, most people with small cell lung cancer survive for about one year; less than seven percent survive 5 years.  Non-small cell lung cancer is divided into three main subtypes: adenocarcinoma, squamous cell carcinoma, and large cell lung carcinoma. Adenocarcinoma arises from the cells that line the small air sacs (alveoli) located throughout the lungs. Squamous cell carcinoma arises from the squamous cells that line the passages leading from the windpipe to the lungs (bronchi). Large cell carcinoma describes non-small cell lung cancers that do not appear to be adenocarcinomas or squamous cell carcinomas. As the name suggests, the tumor cells are large when viewed under a microscope. The 5-year survival rate for people with non-small cell lung cancer is usually between 11 and 17 percent; it can be lower or higher depending on the subtype and stage of the cancer.
How many people are affected by lung cancer ? 
 In the United States, it is estimated that more than 221,000 people develop lung cancer each year. An estimated 72 to 80 percent of lung cancer cases occur in tobacco smokers.  Approximately 6.6 percent of individuals will develop lung cancer during their lifetime. It is the leading cause of cancer deaths, accounting for an estimated 27 percent of all cancer deaths in the United States.
What are the genetic changes related to lung cancer ? 
 Cancers occur when genetic mutations build up in critical genes, specifically those that control cell growth and division or the repair of damaged DNA. These changes allow cells to grow and divide uncontrollably to form a tumor. In nearly all cases of lung cancer, these genetic changes are acquired during a person's lifetime and are present only in certain cells in the lung. These changes, which are called somatic mutations, are not inherited. Somatic mutations in many different genes have been found in lung cancer cells.  Mutations in the EGFR and KRAS genes are estimated to be present in up to half of all lung cancer cases. These genes each provide instructions for making a protein that is embedded within the cell membrane. When these proteins are turned on (activated) by binding to other molecules, signaling pathways are triggered within cells that promote cell growth and division (proliferation).  Mutations in either the EGFR or KRAS gene lead to the production of a protein that is constantly turned on (constitutively activated). As a result, cells are signaled to constantly proliferate, leading to tumor formation. When these gene changes occur in cells in the lungs, lung cancer develops.  Mutations in many other genes have each been found in a small proportion of cases.  In addition to genetic changes, researchers have identified many personal and environmental factors that expose individuals to cancer-causing compounds (carcinogens) and increase the rate at which somatic mutations occur, contributing to a person's risk of developing lung cancer. The greatest risk factor is long-term tobacco smoking, which increases a person's risk of developing lung cancer 20-fold. Other risk factors include exposure to air pollution, radon, asbestos, or secondhand smoke; long-term use of hormone replacement therapy for menopause; and a history of lung disease such as tuberculosis, emphysema, or chronic bronchitis. A history of lung cancer in closely related family members is also an important risk factor; however, because relatives with lung cancer were likely smokers, it is unclear whether the increased risk of lung cancer is the result of genetic factors or exposure to secondhand smoke.
Is lung cancer inherited ? 
 Most cases of lung cancer are not related to inherited gene changes. These cancers are associated with somatic mutations that occur only in certain cells in the lung.  When lung cancer is related to inherited gene changes, the cancer risk is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to increase a person's chance of developing cancer. It is important to note that people inherit an increased risk of cancer, not the disease itself. Not all people who inherit mutations in these genes will develop lung cancer.

What is (are) cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy ? 
 Cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy, commonly known as CARASIL, is an inherited condition that causes stroke and other impairments.  Abnormalities affecting the brain and other parts of the nervous system become apparent in an affected person's twenties or thirties. Often, muscle stiffness (spasticity) in the legs and problems with walking are the first signs of the disorder. About half of affected individuals have a stroke or similar episode before age 40. As the disease progresses, most people with CARASIL also develop mood and personality changes, a decline in thinking ability (dementia), memory loss, and worsening problems with movement.  Other characteristic features of CARASIL include premature hair loss (alopecia) and attacks of low back pain. The hair loss often begins during adolescence and is limited to the scalp. Back pain, which develops in early to mid-adulthood, results from the breakdown (degeneration) of the discs that separate the bones of the spine (vertebrae) from one another.  The signs and symptoms of CARASIL worsen slowly with time. Over the course of several years, affected individuals become less able to control their emotions and communicate with others. They increasingly require help with personal care and other activities of daily living; after a few years, they become unable to care for themselves. Most affected individuals die within a decade after signs and symptoms first appear, although few people with the disease have survived for 20 to 30 years.
How many people are affected by cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy ? 
 CARASIL appears to be a rare condition. It has been identified in about 50 people, primarily in Japan and China.
What are the genetic changes related to cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy ? 
 CARASIL is caused by mutations in the HTRA1 gene. This gene provides instructions for making an enzyme that is found in many of the body's organs and tissues. One of the major functions of the HTRA1 enzyme is to regulate signaling by proteins in the transforming growth factor-beta (TGF-) family. TGF- signaling is essential for many critical cell functions. It also plays an important role in the formation of new blood vessels (angiogenesis).  In people with CARASIL, mutations in the HTRA1 gene prevent the effective regulation of TGF- signaling. Researchers suspect that abnormally increased TGF- signaling alters the structure of small blood vessels, particularly in the brain. These blood vessel abnormalities (described as arteriopathy) greatly increase the risk of stroke and lead to the death of nerve cells (neurons) in many areas of the brain. Dysregulation of TGF- signaling may also underlie the hair loss and back pain seen in people with CARASIL, although the relationship between abnormal TGF- signaling and these features is less clear.
Is cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy inherited ? 
 As its name suggests, this condition is inherited in an autosomal recessive pattern. Autosomal recessive inheritance means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
