Our goal is to identify genes and biological pathways for the development of kidney failure. Our major discovery efforts are focused on the genetics of IgA nephropathy, the most common glomerulonephritis and the genetics of kidney and the urinary tract (CAKUT), the most common cause of kidney failure in children. In parallel, we study the applications of genomic medicine to clinical care for patients with kidney disease.
Recent advances in genome sequencing have provided fundamental insights into many diseases, enabling patient-targeted surveillance, therapy, prognosis, and counseling. While this led to widespread enthusiasm about the potential of genomics to transform clinical care, many challenges still need to be resolved before cost-effective clinical sequencing becomes routine. Gharavi’s lab has been investigating many aspects of these challenges, and when in 2019 The Center for Precision Medicine and Genomics (CPMG) was established under the leadership of Dr. Gharavi, the group joined its efforts to continue addressing challenges of genomic medicine. Through this tight fruitful collaboration, we continue genomic investigation of kidney disorders.
With the broader introduction of genomic medicine in research and clinical care, an increasing number of persons are offered genetic testing. Many factors, including genetic literacy, may impact the utilization of genetic results by patients and their families. We developed a rapid, self-administered measure of genetic literacy, called Genetic Literacy Fast Test (GeneLiFT), which will allow future research to efficiently assess the role of genetic literacy on the clinical impact of genetic testing.
Vesicoureteral reflux (VUR), the retrograde flow of urine from the bladder towards the kidneys, caused by malfunction at the vesicoureteral junction is associated with progressive renal disease and is a common cause of febrile urinary tract infection (UTI) and pediatric kidney failure. VUR has a prevalence of 1-2% in European populations Familial aggregation, with reported occurrence rate of 27-51% among siblings and 66% among offspring of affected individuals, supports a hereditary basis. We conducted the largest VUR copy number variant analysis (CNV) and genome-wide association study (GWAS) to-date, accounting for multiple modes of inheritance and sex- specific effects in VUR. Our dataset included participants from major national cohorts such as RIVUR and CKiD.
Kidney transplantation is the best treatment for end-stage kidney failure, but rejection by the recipient’s immune system remains a major problem. In collaboration with the Kiryluk lab, we studied whether genetic mismatch between donor and recipient can explain kidney transplant rejection.
Exome sequencing (ES) is quickly emerging as a first-line diagnostic tool in clinical medicine, but its utility has not been investigated for the majority of constitutional disorders in adults, including for chronic kidney disease (CKD), which collectively affects more than 1 in 10 individuals globally. Thus, we performed ES in a combined cohort of 3,315 ethnically diverse patients with all-cause CKD, 91.6% of whom were adults, reflecting the demographics of the greater CKD patient population.
The Gharavi lab is pursuing multiple local and multicenter studies to investigate the genetic causes of kidney diseases. We are also conducting several genetic studies generated through the Precision Medicine Initiative. In particular, we are currently enrolling participants in the following studies:
We would like to invite you, your child, or another family member for our study if you have been diagnosed with any kind of kidney disease, in particular if you have one or more of the following conditions:
A signed consent form and a blood sample are required to participate in any of the above studies. Samples can be collected during an in-person appointment or can be shipped to our lab. Also as a part of our studies, we offer free clinic consultations for familial forms of kidney disease.
If you are interested in participating in our studies or have any questions, please contact us at email@example.com
The Kidney Genetics Clinic utilizes a multidisciplinary team of clinicians and genetic counselors, as well as state of the art diagnostic techniques, to provide comprehensive genetic services for adult patients with rare and inherited forms of kidney disease.
These services include: Comprehensive medical evaluation for genetic forms of kidney disease
We have pre- and post-doctoral positions available for highly qualified candidates interested in mammalian genetics and genomics. Prior experience in molecular genetics, statistics or bioinformatics is preferred. for inquiries, please email firstname.lastname@example.org by including your CV.
