The tw18 deletion extends over 4.3 Mbp of Chromosome 17. (A) Number of reads obtained by next generation sequencing of tw18/+ derived genomic DNA mapped to position Chr 17:17000000-25090000. The 3′ end of the deletion is found approximately at position Chr 17:23600000 (asterisk) whereas the 5′ end was roughly positioned between Chr 17: 18.4-19.4 Mb. (B) The presence of DNA elements around the region determined to contain the proximal breakpoint were analyzed by PCR. DNA fragments obtained by PCR amplification and visualized by gel electrophoresis; homozygous tw18 genomic DNA (lower panel) was amplified up to position Chr 17:19.19 Mb, whereas amplicons were absent from position Chr 17:19.33 Mb, indicating that the deletion starts between position 19.19 and 19.33 Mb. (C) Rough functional assignment of the 74 genes deleted in tw18.
