The American Society of Human Genetics (ASHG) convention—a companion convention to the European Society of Human Genetics (ESHG) convention—is without doubt one of the largest annual worldwide conferences of human genetics researchers and professionals. The convention consists of a wide range of scientific analysis classes within the type of featured plenary summary talks, invited talks, platform displays, and poster classes. Along with these classes, the exhibitor convention—one of the vital intensive conferences of trade consultants and biotechnology corporations—additionally befell on the ASHG convention.
Roughly 7000 registrants—together with researchers (each seasoned and early), genetic counsellors, and trade consultants—attended this yr’s in-person ASHG assembly on the Los Angeles Conference Heart in California from October 25 to 29, 2022. The DNA Genotek workforce participated in each the scientific analysis classes and exhibitor convention; we had been delighted to work together in individual with the human genetics analysis group and trade consultants at ASHG 2022.
For these unable to attend, the 5-day convention coated a number of matters starting from genetic insights into the COVID-19 pandemic to the expansion of the African genomics ecosystem. A number of of the 17 plenary talks and 22 platform displays touched on shared themes. Highlights from the convention have been summarized beneath.
Put up-pandemic, what have we discovered about COVID-19?
During the last two years, SARS-CoV-2 has motivated researchers to study extra in regards to the virus and the COVID-19 pandemic, turning into a cornerstone session at a number of scientific conferences. As a virus infecting a human host, host genetics play an necessary function within the acquisition and presentation of COVID-19.
At ASHG 2022, 4 invited audio system every gave a brief presentation describing varied approaches and facets of analysis on the COVID-19 pandemic together with the usage of multimodal proteomics and community analyses to determine molecular determinants of virus-host interplay, the scientific implications of the pandemic together with genetic threat, the genetics behind vaccine side-effects, and the classes discovered from lengthy COVID.
When conducting genome-wide affiliation research (GWAS) on COVID-19, one of many audio system introduced up an necessary level: such research should take into account environmental modifications—i.e., the vaccination standing, of the individuals. In her presentation, Dr. Elizabeth Cirulli (Ph.D.), Affiliate Director at Helix, San Mateo, California, mentioned her group’s efforts to provide the primary profitable GWAS of vaccine reactogenicity, acknowledging that their research got here out similtaneously 23andMe’s research.

The worth of together with range in sequencing initiatives and databases
A number of platform displays described the significance of contemplating human ancestry in populations when finding out ailments reminiscent of kind 2 diabetes, idiopathic pulmonary fibrosis, inflammatory bowel ailments, and alcohol and tobacco addictions. Many presenters famous that the majority prior research on these ailments had been carried out with populations of European descent, representing each an moral bias and analysis limitation.
From a analysis perspective, incorporating understudied and/or ethnically numerous populations (e.g., East Asian, African, Hispanic, South Asian) can present larger perception into illness etiologies as populations will be heterogeneous when it comes to illness threat or presentation. In a single notable instance, the usage of a worldwide multi-ancestry research inhabitants facilitated the identification of seven novel loci related to idiopathic pulmonary fibrosis. Had the research been restricted to solely a European inhabitants, just one locus would have been recognized.
In one other instance highlighting the significance of finding out numerous populations, one presenter described the human genetic variation at tandem repeats—extremely variable areas of the genome that include repeating sequence motifs consisting of a number of nucleotides. The researchers discovered that tandem repeat expansions will be missed in an ethnically uniform inhabitants as some tandem repeat expansions are population-specific (e.g., a CAG growth within the CA10 gene was solely particularly expanded in an African inhabitants).
Some of the well-attended classes throughout the convention was the Presidential Symposium presentation on African Genomics, which offered perception into the analysis, expertise, and infrastructure advances by the African analysis group. 4 key audio system—Dr. Christian Happi (Ph.D.), Dr. Julie Makani (Ph.D.), Dr. Mayowa Owolabi (M.D.), and Dr. Nicola Mulder (Ph.D.)—gave a collection of 10-minute talks describing their illness analysis (e.g., Ebola, sickle cell illness, stroke) and talked about a variety of initiatives and initiatives (e.g., Human Heredity and Well being in Africa or H3Africa, H3ABioNet, and so forth.) that contain the African group. As famous by one speaker, the discoveries popping out of the African analysis group will not be simply of curiosity to African folks (an understudied inhabitants), however to others exterior the group.
A number of displays and posters used sequencing knowledge from the All of Us mission—a extra ethnically numerous cohort—for his or her research. All of Us is a Nationwide Institute of Well being (NIH) initiative that goals to enroll a million or extra folks throughout the U.S. to assemble one of the vital numerous well being databases in historical past.
Getting probably the most out of sequencing outcomes
On the ASHG 2022 convention, a devoted group of platform displays centered on maximizing the output and outcomes acquired from sequencing knowledge, and several other such displays had been within the context of most cancers analysis. Leveraging off-target reads in scientific tumor sequencing, using an built-in method the place RNA sequencing evaluation enhances DNA sequencing, and evaluating exome and panel germline sequencing had been only a subset of the displays concerning this matter. Different talks shared varied novel instruments and approaches (e.g., GenePy, SUsPECT, alternative of human reference genome used) to take advantage of sequencing knowledge used for diagnostic functions.
The query of whether or not focused panel testing (the place solely a subset of “goal” genes or loci are sequenced for disease-causing mutations) or extra expansive sequencing efforts (entire exome sequencing; WES, or entire genome sequencing; WGS) for most cancers and different ailments was raised in a number of disease-focused talks that checked out scientific analysis as a subject. For instance, one notable advantage of WGS is the flexibility to calculate polygenic threat scores.
Some researchers shared outcomes highlighting the advantages related to focused panel screening (as exemplified when screening for metabolic problems), whereas different talks centered on the screening advantages related to WGS (as exemplified by the presentation by PerkinElmer Genomics on pediatric screening). In a single presentation that assessed value and diagnostic yield of WGS versus microarray screening in sufferers with neurodevelopmental problems, the associated fee per identified affected person was proven to be 38% decrease with WGS. One other presentation described how in the UK, a number of initiatives (together with the 100,000 Genomes Mission) at the moment goal to combine genomics into healthcare.
