Summary
Re-analyzing patient genomic data with updated gene panels improves diagnoses. This study tracked changes in rare disease gene panels, showing significant increases in diagnostic genes over time, highlighting the need for dynamic re-analysis strategies.
Area of Science:
- Genomics
- Rare Diseases
- Clinical Diagnostics
Background:
- Re-analysis of genomic data enhances diagnostic yields in patients lacking a molecular diagnosis.
- The discovery and refinement of gene-disease relationships are key drivers for identifying new diagnoses.
Purpose of the Study:
- To investigate how incorporating new knowledge into virtual diagnostic gene panels impacts re-analysis potential.
- To examine the evolution of gene content in rare disease panels and its effect on diagnostic capabilities.
Main Methods:
- Utilized PanelApp Australia to track changes in 112 rare disease panels from 2019 to 2022.
- Categorized panels into Specific and Broad rare disease indications to analyze granular changes in gene composition.
Main Results:
- Diagnostic gene content increased in 82% of Specific and 97% of Broad rare disease panels.
- Median gene gains were 4 for Specific panels (range 0-63) and 27 for Broad panels (range 0-432).
- Panel evolution rates and composition changes varied significantly, as shown by monthly snapshots.
Conclusions:
- Dynamic changes in gene-disease associations necessitate adaptive re-analysis strategies.
- Re-analysis frequency should be informed by the availability of new genetic information rather than fixed time intervals.

02:54Evolutionary Relationships through Genome Comparisons
5.7K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

02:05Gene Evolution - Fast or Slow?
7.0K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

02:32Exon Recombination
3.5K
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.
Exon shuffling follows “splice frame rules.” Each exon...

03:21Genome Size and the Evolution of New Genes
7.9K
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

02:37Gene Duplication and Divergence
6.0K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...
