Abstract

PGD for HLA typing is a procedure that can be performed when an affected child requires a transplant to treat a non-hereditary disorder related to the hematopoietic and/or immune system. Hematopoietic stem cell transplantation from an HLA-identical donor provides the best treatment option. Three conventional ovarian stimulation procedures for IVF were performed in a couple with a 10-year-old child diagnosed with T-cell acute lymphoblastic leukemia of high risk. Trophectoderm biopsy and aCGH examination were performed on 15 blastocysts, three on the first IVF procedure, four on the second cycle, and eight on the third. Three euploid blastocysts HLA-compatible with the genome of the affected child were identified. One euploid blastocyst HLA-compatible with the affected child was warmed and transferred, resulting in an HLA-matched live birth. In conclusion, combined aCGH for aneuploidy screening and Karyomapping may be performed in a single biopsy procedure.

Keywords: HLA matching; aCGH; karyomapping.
