Also see Issue #167

Appears to be inter-chromosomal translocation with chr13 (approx 28kb region) coverage of chr3 prior to translocation ~200, then drops to ~100X at join with chr13 This region of chr3 is inverted then joins to chr13 , issue 167 also shown Screenshot 2024-09-30 at 8 42 48 AM

Ribbon shows translocation only adjacent to inverted chr3 from issue #167 Screenshot 2024-10-03 at 1 25 03 PM

Occurs on one haplotype Approx half of reads map to chr3 other half has supplementary alignments to chr13. Assembly also shows translocation on one haplotype. Screenshot 2024-10-03 at 1 27 59 PM

Breakpoint appears correct Left breakpoint has 1 bp homology with right, "A". Left aligning breakpoint appears to be correct. Screenshot 2024-10-03 at 4 39 12 PM

right end of translocated region is the left breakpoint of issue #167, position 139998693 Screenshot 2024-10-03 at 1 38 34 PM
