Chromosomal inversions (INVs) are particularly challenging to detect due their copy-number neutral state and association with repetitive regions. Inversions represent about 1/20 of all balanced structural chromosome aberrations can lead disease by gene disruption or altering regulatory regions dosage-sensitive genes in cis . Short-read genome sequencing (srGS) only resolve ∼70% cytogenetically visible referred clinical diagnostic laboratories, likely breakpoints Here, we study 12 long-read (lrGS) ( n = 9) srGS 3) nine them. In four cases, the inversion breakpoint region was missing from at least one human reference genomes (GRCh37, GRCh38, T2T-CHM13) a agnostic analysis needed. One these an INV9 mappable de novo assembled lrGS data using T2T-CHM13 disrupts EHMT1 consistent Mendelian diagnosis (Kleefstra syndrome 1; MIM#610253). Next, pairwise comparison between T2T-CHM13, GRCh37, as well chimpanzee bonobo, show that hundreds megabases sequence reference, highlighting primate contribute genomic diversity. Aligning population indicated variable individuals. Our emphasizes is necessary maximize value for optimal detection diagnostics. These results highlight importance leveraging diverse comprehensive unsolved molecular cases rare diseases.
