Hela Azaiez,PhD at the University of Iowa, uses SVS to understand the molecular genetics of hearing loss
Hearing loss is the most common sensory defect in humans. It affects roughly 1 in 500 newborns, and by the age of 80 approximately 50% of people have some type of hearing loss. Hearing loss has become an enormous burden in healthcare. Perhaps more importantly, studies have shown that hearing loss also affects one?s quality of life, lowering social interactions as communication deteriorates. However, for Hela Azaiez, an associate research scientist at the University of Iowa, the commonality of hearing diseases is what makes them so interesting to study.
Azaiez is a part of the Molecular Otolaryngology and Renal Research Laboratories (MORL) directed by Pr. Richard Smith at the University of Iowa, which focuses on hereditary hearing loss and renal diseases.

Using linkage and association studies to better understand the genetic mechanisms of inherited eye disease at the NIH - NEI
Dr. James Fielding Hejtmancik and his team at the National Eye Institute?s Ophthalmic Genetics and Visual Function branch, use linkage and association studies to better understand the genetic mechanisms of inherited eye disease. The team investigates both Mendelian and complex diseases as well as functional work with a focus on cataracts, retinal degenerations, myopia and corneal dystrophies. ?If it effects vision, we pretty much study it,? commented Dr. Hejtmancik, the lab's director.
With uncertain funding levels, the small lab has created strong collaborations across the globe with other centers and labs studying eye disease. Their collaborations provide access to larger data sets which in turn allow for more broad analysis. Currently, the lab is completing and publishing five to ten studies a year with a focus on linkage analysis and candidate gene studies.
Founded by Hans Zellweger in the 1960?s, The Shivanand R. Patil Cytogenetics and Molecular Lab at the University of Iowa has a long history of clinical testing, seeing 45 years of advancements. Today, the lab is mainly focused on oncology, pre and post-natal genetics testing and serves the University of Iowa Hospitals and Clinics as well as the University of Iowa Stead Family Children?s Hospital. In last year alone they have performed over 5,500 clinical tests.
When the lab?s director, Dr. Benjamin Darbro purchased Illumina?s NextSeq 500, he did so with the vision of being able to offer phenotype-focused gene sequencing panels. Darbro knew this goal would require an informatics pipeline with the same level of sophistication the lab developed for their research side, but one that would fit within the framework required of clinical testing.
Scott Diehl, a professor and geneticist at Rutgers School of Dental Medicine, performs family studies, association studies and gene mapping to discover the genetic causes of periodontal diseases. Originally, Diehl had a large team of bioinformaticians in the lab to help with his analyses, but the high cost of such personnel created the need for another solution. With Golden Helix?s SVS software, Diehl and his small lab team are able to rapidly conduct a wide range of statistical analyses on their data without having to spend all their time bogged down in difficult command language.
Much of Diehl?s work is focused on periodontal diseases and tooth decay, two conditions with substantial heritability. The main goal of the lab is to find the specific genetic variants that underlie the heritability to understand the diseases? mechanisms.
Dr. Peter K. Gregersen, Head of the Center for Genomics and Human Genetics at the Feinstein Institute for Medical Research, utilizes GWAS, targeted arrays, and sequencing technologies to identify genes associated with human autoimmune disorders. An increasing number of projects generated the need for an analytical tool that would allow the biologists to find significant data quickly. "I have always thought that putting the analytic power in the hands of the biologists who are thinking about the disease is really important," says Gregersen. With SNP & Variation Suite™ (SVS) software, Gregersen can do just that.
