Genetic analysis and clinical significance of a rare t(1;12)(q21;p13) in a patient with high-risk myelodysplastic syndrome.

ABSTRACT: To explore the genetic and clinical features of a rare t(1;12)(q21;p13) in a patient with myelodysplastic syndrome (MDS). A 53-year-old male was diagnosed as high-risk MDS, and died in a short period. A complete cytogenetic analysis of bone marrow by conventional G-banding karyotyping was performed at the time of initial evaluation. On the basis of chromosome karyotype, interphase and metaphase fluorescence in-situ hybridization (FISH) were carried out to further confirm the abnormal karyotypes. Reverse-transcription polymerase chain reaction (RT-PCR) was performed to determine ETV6/ARNT fusion gene status. G-banding revealed karyotype 47, XY, +8, der(12) t(1;12)(q21;p13). FISH with the centromere 8 probe verified the trisomy 8, and the ETV 6 break-apart probe suggested heterozygous loss o
