Germline sequence variation within the ribosomal DNA is associated with human complex traits.

Germline rDNA sequence variants (SNVs, indels) associated with human complex traits

This Cell Genomics study demonstrates for the first time that germline sequence variants in ribosomal DNA (rDNA) — a region long inaccessible to standard NGS — are associated with human complex traits. Using long-read approaches, the authors characterize intra- and inter-individual rDNA variation and establish phenotypic associations.

rDNA has traditionally been ignored in NGS analyses due to its multicopy repetitive nature. Demonstrating that its variants contribute to complex traits opens a new genomic compartment made accessible by long-read sequencing.
