The ADA deficiency phenotypic spectrum includes typical early-onset severe combined immunodeficiency (ADA-SCID), diagnosed in infancy (about 80% of individuals), and less severe &quot;delayed&quot; or &quot;late-onset&quot; combined immunodeficiency (ADA-CID), diagnosed in older children and adults (15%-20% of individuals). Some healthy individuals who are deficient in red blood cell ADA (termed &quot;partial ADA deficiency&quot;) have been discovered by screening populations or relatives of individuals with ADA-SCID. Newborn screening (NBS) for SCID uses extracts from Guthrie card dried blood spots to measure T-cell receptor excision circle (TREC) DNA by polymerase chain reaction (PCR). Screening specific for ADA deficiency can also be performed by detection of elevated levels of adenosine (Ado) and deoxyadenosine (dAdo) by tandem mass spectrometry (TMS). Both techniques can identify ADA-SCID before affected infants become symptomatic. Untreated ADA-SCID presents as life-threatening opportunistic illnesses in the first weeks to months of life with poor linear growth and weight gain secondary to persistent diarrhea, extensive dermatitis, and recurrent pneumonia. Skeletal abnormalities affecting ribs and vertebra, pulmonary alveolar proteinosis, hemolytic anemia, neurologic abnormalities, and transaminitis may also suggest untreated ADA-SCID. Characteristic immune abnormalities are lymphocytopenia (low numbers of T, B, and NK cells) combined with the absence of both humoral and cellular immune function. If immune function is not restored with enzyme replacement therapy (ERT), gene therapy, or hematopoietic stem cell transplantation (HSCT), children with ADA-SCID rarely survive beyond age one to two years. NBS for SCID does not identify individuals with the ADA-CID phenotype whose TREC numbers are above the threshold values of most screening laboratories. However, ADA-CID is identified by TMS NBS since the ADA substrates Ado and dAdo are increased. As TMS NBS for Ado/dAdo is not yet widely performed, individuals with ADA-CID are more often clinically diagnosed between ages one and ten years (&quot;delayed&quot; onset), or less often in the second to fourth decades (&quot;late&quot;/&quot;adult&quot; onset). Because the immunologic abnormalities are less pronounced than those of ADA-SCID, infections in ADA-CID may not be life-threatening and include recurrent otitis media, sinusitis, upper respiratory infections, and human papilloma viral infections. Untreated individuals with ADA-CID can develop over time chronic pulmonary disease, autoimmunity, atopic disease with elevated immunoglobulin E, and malignancy." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln"><div class="excerpt">Excerpted from the <i>GeneReview: </i><a href="/books/NBK1483" target="_blank">Adenosine Deaminase Deficiency</a></div><div>Adenosine deaminase (ADA) deficiency is a systemic purine metabolic disorder that primarily affects lymphocyte development, viability, and function. The ADA deficiency phenotypic spectrum includes typical early-onset severe combined immunodeficiency (ADA-SCID), diagnosed in infancy (about 80% of individuals), and less severe "delayed" or "late-onset" combined immunodeficiency (ADA-CID), diagnosed in older children and adults (15%-20% of individuals). Some healthy individuals who are deficient in red blood cell ADA (termed "partial ADA deficiency") have been discovered by screening populations or relatives of individuals with ADA-SCID. Newborn screening (NBS) for SCID uses extracts from Guthrie card dried blood spots to measure T-cell receptor excision circle (TREC) DNA by polymerase chain reaction (PCR). Screening specific for ADA deficiency can also be performed by detection of elevated levels of adenosine (Ado) and deoxyadenosine (dAdo) by tandem mass spectrometry (TMS). Both techniques can identify ADA-SCID before affected infants become symptomatic. Untreated ADA-SCID presents as life-threatening opportunistic illnesses in the first weeks to months of life with poor linear growth and weight gain secondary to persistent diarrhea, extensive dermatitis, and recurrent pneumonia. Skeletal abnormalities affecting ribs and vertebra, pulmonary alveolar proteinosis, hemolytic anemia, neurologic abnormalities, and transaminitis may also suggest untreated ADA-SCID. Characteristic immune abnormalities are lymphocytopenia (low numbers of T, B, and NK cells) combined with the absence of both humoral and cellular immune function. If immune function is not restored with enzyme replacement therapy (ERT), gene therapy, or hematopoietic stem cell transplantation (HSCT), children with ADA-SCID rarely survive beyond age one to two years. NBS for SCID does not identify individuals with the ADA-CID phenotype whose TREC numbers are above the threshold values of most screening laboratories. However, ADA-CID is identified by TMS NBS since the ADA substrates Ado and dAdo are increased. As TMS NBS for Ado/dAdo is not yet widely performed, individuals with ADA-CID are more often clinically diagnosed between ages one and ten years ("delayed" onset), or less often in the second to fourth decades ("late"/"adult" onset). Because the immunologic abnormalities are less pronounced than those of ADA-SCID, infections in ADA-CID may not be life-threatening and include recurrent otitis media, sinusitis, upper respiratory infections, and human papilloma viral infections. Untreated individuals with ADA-CID can develop over time chronic pulmonary disease, autoimmunity, atopic disease with elevated immunoglobulin E, and malignancy. [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/NBK1483#ada.Summary" target="NBK1483">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1483#ada.GeneReview_Scope" target="NBK1483">GeneReview Scope</a>  |  <a class="medgenPMinfo" href="/books/NBK1483#ada.Diagnosis" target="NBK1483">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1483#ada.Clinical_Characteristics" target="NBK1483">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1483#ada.Genetically_Related_Allelic_Disorder" target="NBK1483">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1483#ada.Differential_Diagnosis" target="NBK1483">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1483#ada.Management" target="NBK1483">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1483#ada.Genetic_Counseling" target="NBK1483">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1483#ada.Resources" target="NBK1483">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1483#ada.Molecular_Genetics" target="NBK1483">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1483#ada.Chapter_Notes" target="NBK1483">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK1483#ada.References" target="NBK1483">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />Severe combined immunodeficiency (SCID) resulting from inherited ADA deficiency causes a variable phenotypic spectrum, the most severe being SCID presenting in infancy and usually resulting in early death. Ten to 15% of patients have a 'delayed' clinical onset by age 6 to 24 months, and a smaller percentage of patients have 'later' onset, diagnosed from ages 4 years to adulthood, showing less severe infections and gradual immunologic deterioration. Finally, 'partial' ADA deficiency occurs in a subset of immunocompetent individuals who show decreased enzyme activity in erythrocytes, but retain substantial enzyme activity ranging from 5 to 80% of normal in leukocytes and other nucleated cells (summary by Arredondo-Vega et al., 1994). ADA deficiency accounts for approximately 15% of all SCID cases and one-third of cases of autosomal recessive SCID (Hershfield, 2003).  <a target="_blank" href="http://www.omim.org/entry/102700">http://www.omim.org/entry/102700</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />Adenosine deaminase (ADA) deficiency is a disorder that affects the immune system. Specifically, ADA deficiency impairs the development and function of immune cells called lymphocytes. Lymphocytes are white blood cells that help the body fight infections. As a result, people with ADA deficiency often develop pneumonia, chronic diarrhea, and widespread skin rashes. Additional signs and symptoms of ADA deficiency include slow growth and developmental delays.<br /><br />About 80 percent of individuals with ADA deficiency also have severe combined immunodeficiency (SCID). People with SCID lack virtually all immune protection from bacteria, viruses, and fungi. They are prone to repeated and persistent infections that can be serious or life-threatening. These infections are often caused by "opportunistic" organisms that ordinarily do not cause illness in people with a normal immune system. People with ADA deficiency with SCID (ADA-SCID) typically develop health problems within the first 6 months of life. Without treatment, these babies usually do not survive past age 2.<br /><br />About 15 to 20 percent of people with ADA deficiency develop health problems that begin between 1 and 10 years of age (delayed onset) or in adulthood (late onset). In people with this form of ADA deficiency (known as delayed or late-onset combined immunodeficiency or ADA-CID), the immune deficiency tends to be less severe than in people with ADA-SCID. People with ADA-CID typically have recurrent upper respiratory and ear infections. Over time, affected individuals may develop chronic lung damage, malnutrition, and other health problems.<br /><br />In some individuals, ADA deficiency only impacts red blood cells. Since white blood cells are not affected, these individuals have normal immune systems. This form of the condition is known as partial ADA deficiency. Individuals with this form do not have any health problems related to the condition. They often only find out they have ADA deficiency when they undergo testing because of an affected relative or during a normal health screening.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/adenosine-deaminase-deficiency">https://medlineplus.gov/genetics/condition/adenosine-deaminase-deficiency</a></div></div>

Histologic features include an increase in the mesangial matrix, thickened glomerular basement membrane, tubular casts, and interstitial inflammation. Diffuse mesangial sclerosis presents with nephrotic syndrome at birth or within the first year of life. Glomeruli are small and condensed in appearance, with early lesions showing increased loose mesangial collagen that progress to sclerosis with dense collagen without hypercellularity. Podocytes do not show hyperplasia but may be immature and cobblestone-like.
