Current knowledge of lymphoid and hematopoietic development in mice, as well as understanding regulators of human hematopoiesis, have led to the recent discovery of genetic causes of bone marrow failure disorders. However, in the absence of mutations of specific genes or a distinct clinical phenotype, many cases of aplastic anemia are labeled as idiopathic, while congenital immune deficiencies are described as combined immune deficiency.<\/jats:p><\/jats:sec><jats:sec><jats:title>Procedure<\/jats:title><jats:p>We describe the case of a 33\u2010week gestation age male with severe polyhydramnios, hydrops, and ascites who was noted to be pancytopenic at birth. Bone marrow examination revealed a hypocellular marrow with absent myelopoiesis. An immune workup demonstrated profound B lymphopenia, near absent NK cells, and normal T cell number. Due to the similarity of the patient's phenotype with the IKAROS knockout mouse, studies were performed on bone marrow and peripheral blood to assess a potential pathogenic role of Ikaros.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>DNA studies revealed a point mutation in one allele of the IKAROS gene, resulting in an amino acid substitution in the DNA\u2010binding zinc finger domain. Functional studies demonstrated that the observed mutation decreased Ikaros DNA\u2010binding affinity, and immunofluorescence microscopy revealed aberrant Ikaros pericentromeric localization.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our report describes a novel case of congenital pancytopenia associated with mutation of the IKAROS gene.
