Physical abnormalities, present in approximately 75% of affected individuals, include one or more of the following: short stature, abnormal skin pigmentation, skeletal malformations of the upper and/or lower limbs, microcephaly, and ophthalmic and genitourinary tract anomalies. Progressive bone marrow failure with pancytopenia typically presents in the first decade, often initially with thrombocytopenia or leukopenia. The incidence of acute myeloid leukemia is 13% by age 50 years. Solid tumors particularly of the head and neck, skin, and genitourinary tract are more common in individuals with FA." /><meta name="robots" content="index,nofollow,noarchive" />

Physical abnormalities, present in approximately 75% of affected individuals, include one or more of the following: short stature, abnormal skin pigmentation, skeletal malformations of the upper and/or lower limbs, microcephaly, and ophthalmic and genitourinary tract anomalies. Progressive bone marrow failure with pancytopenia typically presents in the first decade, often initially with thrombocytopenia or leukopenia. The incidence of acute myeloid leukemia is 13% by age 50 years. Solid tumors particularly of the head and neck, skin, and genitourinary tract are more common in individuals with FA. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK1401#fa.Summary" target="NBK1401">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1401#fa.Diagnosis" target="NBK1401">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1401#fa.Clinical_Characteristics" target="NBK1401">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1401#fa.Genetically_Related_Allelic_Disorders" target="NBK1401">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1401#fa.Differential_Diagnosis" target="NBK1401">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1401#fa.Management" target="NBK1401">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1401#fa.Genetic_Counseling" target="NBK1401">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1401#fa.Resources" target="NBK1401">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1401#fa.Molecular_Genetics" target="NBK1401">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1401#fa.Chapter_Notes" target="NBK1401">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK1401#fa.References" target="NBK1401">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />Fanconi anemia (FA) is a clinically and genetically heterogeneous disorder that causes genomic instability. Characteristic clinical features include developmental abnormalities in major organ systems, early-onset bone marrow failure, and a high predisposition to cancer. The cellular hallmark of FA is hypersensitivity to DNA crosslinking agents and high frequency of chromosomal aberrations pointing to a defect in DNA repair (summary by Deakyne and Mazin, 2011).&#13;
Patients with FANCB mutations often present with multiple additional congenital anomalies, including the constellation of features designated VACTERL-H (see 314390), for vertebral defects, anal atresia, tracheoesophageal fistula, esophageal atresia, radial or renal dysplasia, and hydrocephalus. Many patients with these features die in early infancy before developing anemia (McCauley et al., 2011).&#13;
For additional general information and a discussion of genetic heterogeneity of Fanconi anemia, see 227650.  <a target="_blank" href="http://www.omim.org/entry/300514">http://www.omim.org/entry/300514</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />More than half of people with Fanconi anemia have physical abnormalities. These abnormalities can involve irregular skin coloring such as unusually light-colored skin (hypopigmentation) or café-au-lait spots, which are flat patches on the skin that are darker than the surrounding area. Other possible symptoms of Fanconi anemia include malformed thumbs or forearms and other skeletal problems including short stature; malformed or absent kidneys and other defects of the urinary tract; gastrointestinal abnormalities; heart defects; eye abnormalities such as small or abnormally shaped eyes; and malformed ears and hearing loss. People with this condition may have abnormal genitalia or malformations of the reproductive system. As a result, most affected males and about half of affected females cannot have biological children (are infertile). Additional signs and symptoms can include abnormalities of the brain and spinal cord (central nervous system), including increased fluid in the center of the brain (hydrocephalus) or an unusually small head size (microcephaly).<br /><br />The major function of bone marrow is to produce new blood cells. These include red blood cells, which carry oxygen to the body's tissues; white blood cells, which fight infections; and platelets, which are necessary for normal blood clotting. Approximately 90 percent of people with Fanconi anemia have impaired bone marrow function that leads to a decrease in the production of all blood cells (aplastic anemia). Affected individuals experience extreme tiredness (fatigue) due to low numbers of red blood cells (anemia), frequent infections due to low numbers of white blood cells (neutropenia), and clotting problems due to low numbers of platelets (thrombocytopenia). People with Fanconi anemia may also develop myelodysplastic syndrome, a condition in which immature blood cells fail to develop normally.<br /><br />Individuals with Fanconi anemia have an increased risk of developing a cancer of blood-forming cells in the bone marrow called acute myeloid leukemia (AML) or tumors of the head, neck, skin, gastrointestinal system, or genital tract. The likelihood of developing one of these cancers in people with Fanconi anemia is between 10 and 30 percent.<br /><br />Fanconi anemia is a condition that affects many parts of the body. People with this condition may have bone marrow failure, physical abnormalities, organ defects, and an increased risk of certain cancers.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/fanconi-anemia">https://medlineplus.gov/genetics/condition/fanconi-anemia</a></div></div>

<div class="spaceAbove">In utero, the ductus arteriosus (DA) serves to divert ventricular output away from the lungs and toward the placenta by connecting the main pulmonary artery to the descending aorta. A patent ductus arteriosus (PDA) in the first 3 days of life is a physiologic shunt in healthy term and preterm newborn infants, and normally is substantially closed within about 24 hours after bith and completely closed after about three weeks. Failure of physiologcal closure is referred to a persistent or patent ductus arteriosus (PDA). Depending on the degree of left-to-right shunting, PDA can have clinical consequences.</div>

About 75% of these cases are classified as idiopathic (Young, 2000). In about 15% of cases a drug or infection can be identified that precipitates the aplasia, although why only some individuals are susceptible is unclear. In about 5 to 10% of patients, the aplastic anemia is constitutional--i.e., is familial or presents with one or more associated somatic abnormalities (summary by Vulliamy et al., 2002).</div>
