A rare case of acquired immunodeficiency associated with myelodysplastic syndrome.

ABSTRACT:

Background

Pediatric myelodysplastic syndromes (MDS) display clonal genomic instability that can lead to acquisition of other hematological disorders, usually by loss of heterozygosity. Immunodeficiency caused by uniparental disomy (UPD) has not previously been reported.

Methods

We investigated a 13-year-old boy who suffered from recurrent infections and pancytopenia for 1 year. Both the comet assay and chromosome breakage analysis were normal, but the bone marrow showed evidence of dysplasia characteristic of MDS. With his normal sister as donor, he underwent failed hematopoietic stem cell transplantation (HSCT) with reduced intensity conditioning (RIC) followed by successful HSCT with myeloablative conditioning (MAC). We used single nucleotide polymorphism (SNP) array, tar
