To develop and validate a cytogenetic approach combining chromosome flow sorting and DOP-PCR amplification to identify chromosomal translocation breakpoints in cell lines with complex rearrangements.
Flow-sorted 500 copies of derivative chromosomes from two lymphoblastoid cell lines and one medullary thyroid carcinoma cell line harboring translocations near the MEN 2A locus.
Amplified sorted chromosomal DNA using degenerate oligonucleotide-primed PCR (DOP-PCR) to create probe pools for fluorescence in situ hybridization (FISH) on normal metaphase spreads.
Defined specific translocation breakpoints in bands p15, q11.2, and q21 of chromosome 10 across the evaluated cell lines.
Successfully refined previously uncertain cytogenetic mapping data in two of the three analyzed cell lines.
