<span class="mim-text-font">
<p>Congenital nonspherocytic hemolytic anemia-9 (CNSHA9) is an X-linked hematologic disorder characterized by onset of mild to moderate red cell anemia soon after birth or in childhood.

The mutations affected a conserved residue in an intrinsically disordered region (IDR) in the C-terminal domain. The mutations, which were found by whole-exome sequencing, were not present in the gnomAD database. Patient-derived erythroid cells showed impaired differentiation, reduced proliferation, and altered morphology compared to controls, which could be partially rescued by expression of wildtype GATA1. Cells transduced with the mutations showed increased erythrocyte ADA levels and increased ADA mRNA levels compared to controls. RNA-seq analysis indicated differential expression of genes involved in hematopoiesis and terminal erythroid maturation. Mouse-derived Gata1-null cells transduced with Gata1 showed induction of Ter119, a marker for erythroid differentiation; cells transduced with the R307C/H mutants had reduced Ter119 expression. The R307C/H mutations partially disrupted a predicted nuclear localization signal, and the mutant proteins showed a 40% reduction in the nucleus and increased retention in the cytoplasm compared to wildtype. RNA-seq analysis results were consistent with altered transcriptional activity of the mutants toward canonical GATA1 target genes. Further studies of mutant cells showed altered chromatin accessibility and DNA binding associated with the mutations, consistent with the observed changes in gene expression that pointed to disrupted transcription regulation. Overall, the findings indicated a primary erythroid defect of terminal differentiation resulting from specific mutations in the GATA1 master transcription factor. <a href="https://pubmed.ncbi.nlm.nih.gov/?term=3164080+35030251" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

<strong>Description</strong>

</h4>
</div>
<span class="mim-text-font">
<p>Congenital nonspherocytic hemolytic anemia-9 (CNSHA9) is an X-linked hematologic disorder characterized by onset of mild to moderate red cell anemia soon after birth or in childhood. The anemia is associated with significantly increased activity of ADA (608958) specifically in erythrocyte precursors. ATP levels may be secondarily decreased. Additional features may include low birth weight, thrombocytopenia, hypospadias, and splenomegaly. Males are preferentially affected, although carrier females may show elevated erythrocyte ADA or mild features (Ludwig et al., 2022). </p>

<span class="mim-text-font">
<p><strong><em>Early Reports without Genetic Confirmation</em></strong></p><p>
Valentine et al. (1977) reported a kindred in which 12 individuals spanning 3 generations had hemolytic anemia associated in increased red cell ADA activity and decreased red cell ATP levels. Both males and females were affected. The anemia was mild and compensated in most cases. ADA activities ranged from 45- to 70-fold greater than controls. The authors concluded that the hemolytic disorder may result from the inability of the red cell to salvage adenine nucleotides upon which nonnucleated erythrocytes, incapable of de novo synthesis, are so dependent. Chottiner et al. (1987) studied the family originally described by Valentine et al. (1977). They verified that red cell ADA-specific activity was 70 to 100 times the normal levels. Western blots demonstrated a corresponding increase in red cell ADA-specific immunoreactive protein. Analysis of genomic DNA showed no evidence for amplification or major structural changes in the ADA gene. ADA-specific mRNA from proband reticulocytes was comparable in size and amount to mRNA from control reticulocytes. This finding excluded increased transcription of the gene or increased stability of red cell ADA mRNA. </p><p>Miwa et al. (1978) reported a 38-year-old Japanese male with compensated hemolytic anemia. His red cells showed moderate stomatocytosis and his red cell ADA activity was 40 times normal. The mother showed a 4-fold increase in red cell ADA; the father's enzyme levels were normal. ADA levels in lymphocytes were nearly normal. Serum uric acid levels were mildly elevated. The authors suggested that the genetic defect probably involves a regulatory gene at a locus separate from the structural locus for ADA on chromosome 20. </p><p>Perignon et al. (1982) reported a 10-year-old boy with severe hemolytic anemia associated with ADA activity at about 85 times the normal range. Evidence was presented that the excessive ADA activity in red cells was due to an abnormal amount of a catalytically and immunologically normal enzyme. </p><p><strong><em>Patients with Confirmed GATA1 Mutations</em></strong></p><p>
Kanno et al. (1988) reported a 10-year-old Japanese boy who presented at birth with pallor, hypospadias, and cryptorchidism. He had persistent hemolytic anemia with reticulocytosis and elevated bilirubin. Bone marrow examination showed hypercellularity and erythroid hyperplasia, and blood smear showed stomatocytosis. The half-life of red cells was decreased, but osmotic fragility was normal. Erythrocyte ADA enzymatic activity was significantly increased at 88.6 IU/gHb; lymphocyte ADA activity was normal. ATP levels were mildly decreased compared to controls. The patient underwent splenectomy at age 11 years, resulting in increased hemoglobin levels. Patient red cells showed elevated rate of ADA synthesis and abnormal accumulation of the ADA protein, with normal mRNA levels. ADA overproduction was not observed in other tissues. Red cell ADA in the mother was mildly increased at 1.74 IU/gHb; ADA in the father was normal. Kanno et al. (1988) concluded that the regulation of protein synthesis was altered in a tissue-specific pattern, namely in erythroid precursors. The patient had 3 sibs, all of whom died in the perinatal period due to congenital heart disease, unknown cause, and erythroblastosis fetalis, respectively; DNA was not available from those individuals. </p><p>Ogura et al. (2016) reported an 18-year-old Japanese man with congenital hemolytic anemia. Other features included low birth weight, hypospadias, splenomegaly, and slightly decreased platelet counts. The anemia was associated with increased erythrocyte ADA (39.7 IU/gHb), representing an over 30-fold elevation of the normal value. Red cell ADA in the mother was mildly increased at 7.4, whereas it was normal in the father. Ludwig et al. (2022) reported that the hemolytic anemia had been apparent at birth and required blood transfusion, with eventual improvement through childhood. At age 17 years, he had an episode of intravascular hemolysis with severe anemia and abnormal morphology on blood smear, including anisocytosis, target cells, and ovalostomatocytes. </p><p>Ludwig et al. (2022) reported a 3-year-old boy, born of unrelated parents of Irish/English origin, who presented soon after birth with macrocytic anemia and thrombocytopenia requiring blood and platelet transfusions. He had a complicated neonatal course with a small ventricular septal defect (VSD), rash, micropenis, hepatosplenomegaly, clubfoot, and required an extensive stay in the NICU. Brain imaging showed extensive neuronal migrational abnormalities with pachygyria, a schizencephalic cleft, and periventricular white matter calcifications. Perinatal infections were excluded. Over time, his only hematologic abnormality was mild macrocytic hemolytic anemia. Erythrocyte ADA was elevated at 14.4 IU/gHb. He was verbal and could stand, but was nonambulatory. Red cell ADA level in the mother was not reported. </p>

<span class="mim-text-font">
<p>In 3 unrelated male patients with CNSHA9, including the patients reported by Kanno et al. (1988) and Ogura et al. (2016), Ludwig et al. (2022) identified hemizygous mutations affecting the same residue in the GATA1 gene (R307C, 305371.0012 and R307H, 305371.0013). The mutations affected a conserved residue in an intrinsically disordered region (IDR) in the C-terminal domain. The mutations, which were found by whole-exome sequencing, were not present in the gnomAD database. Patient-derived erythroid cells showed impaired differentiation, reduced proliferation, and altered morphology compared to controls, which could be partially rescued by expression of wildtype GATA1. Cells transduced with the mutations showed increased erythrocyte ADA levels and increased ADA mRNA levels compared to controls. RNA-seq analysis indicated differential expression of genes involved in hematopoiesis and terminal erythroid maturation. Mouse-derived Gata1-null cells transduced with Gata1 showed induction of Ter119, a marker for erythroid differentiation; cells transduced with the R307C/H mutants had reduced Ter119 expression. The R307C/H mutations partially disrupted a predicted nuclear localization signal, and the mutant proteins showed a 40% reduction in the nucleus and increased retention in the cytoplasm compared to wildtype. RNA-seq analysis results were consistent with altered transcriptional activity of the mutants toward canonical GATA1 target genes. Further studies of mutant cells showed altered chromatin accessibility and DNA binding associated with the mutations, consistent with the observed changes in gene expression that pointed to disrupted transcription regulation. Overall, the findings indicated a primary erythroid defect of terminal differentiation resulting from specific mutations in the GATA1 master transcription factor. </p>

<strong>History</strong>

<span class="mim-text-font">
<p>Glader et al. (1983) suggested that elevated ADA activity is a feature of Blackfan-Diamond anemia (105650). </p><p>Novelli et al. (1986) found a 4-fold increase in red cell ADA in a 16-month-old Libyan infant without hemolytic anemia but with mild anisopoikilocytosis. The parents, who were related as first cousins, and a healthy brother had normal red cell ADA levels. </p><p>In the form of severe combined immunodeficiency with deficiency of ADA (102700), structural changes such as point mutations have been identified in the ADA gene (608958) on chromosome 20 and the deficiency is found in all tissues. In the disorder of ADA excess, only the erythroid elements show the abnormality and the ADA molecule is structurally normal by all the usual criteria, including electrophoretic migration, kinetics for various substrates and inhibitors, heat stability, specific activity, pH optimum, immunologic reactivity, amino acid composition, and peptide patterns. The mutation is presumably in a gene separate from the structural gene for ADA. The study of these families with DNA markers located in the region of the ADA gene on 20q might prove conclusively that the determinant is at a site remote from the ADA gene. Such experiments were performed by Chen et al. (1993), who, to determine whether increased ADA mRNA is due to a cis-acting or a trans-acting mutation, took advantage of a highly polymorphic TAAA repeat located at the tail end of an Alu repeat approximately 1.1 kb upstream of the ADA gene. Using PCR to amplify this region, they identified 5 different alleles in 19 members of an affected family (Valentine et al., 1977). All 11 affected individuals had an ADA allele with 12 TAAA repeats, whereas none of the 8 normal individuals did. They concluded that this disorder results from a cis-acting mutation in the vicinity of the ADA gene. Chen and Mitchell (1994) examined reporter gene activity using constructs containing 10.6 kb of 5-prime flanking sequence and 12.3 kb of the first intron of the ADA gene from normal and mutant alleles. No differences in chloramphenicol acetyltransferase (CAT) activity were found in transient transfection experiments using erythroleukemia cell lines. Furthermore, transgenic mice containing the ADA constructs showed CAT activities in erythrocytes and bone marrow that did not differ between the normal and mutant alleles. Results were interpreted as indicating that the mutation responsible for ADA overexpression is unlikely to reside in the 5-prime and promoter regions or in the regulatory regions of the first intron of the ADA gene. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
