Mann Lab

Approximately 20-30% of children with chronic kidney disease have an underlying genetic cause of their disease. Our lab is interested in better understanding the genetic landscape of kidney disease and the mechanisms by which these genetic changes affect kidney development and function.

We apply human genetics and basic cell biology techniques to study how genetic changes impact kidney function. Dr. Mann also co-directs the Kidney Genetics Clinic at Nationwide Children's Hospital, and we integrate clinical genetics with basic research with the goal of improving diagnosis, care and future treatments for children with inherited kidney conditions.

Genetic Basis of Lower Urinary Tract Dysfunction
Diagram illustrating the cellular and molecular components of the lower urinary tract. At the top, a large yellow urothelial cell with purple hair-like structures is shown. Below are gray interstitial cells and green afferent nerves, with blue efferent nerves to the right. The detrusor smooth muscle is depicted in pink at the bottom, containing black actin filaments and orange myosin heads. Labeled genes and proteins include ACTA2, ACTG2, MYLK, MYH11 for actin-myosin contraction, CHRM3 and CHRNA3 for synaptic transmission, and LRIG2 and HPSE2 for nerve patterning.

Lower urinary tract dysfunction can cause significant distress for patients. Our previous studies discovered that mutations in an acetylcholine receptor, CHRNA3, can cause recurrent urinary tract infections and bladder dysfunction. We are applying genomic tools to discover novel genetic causes for lower urinary tract dysfunction and to understand the functional consequences of these genetic changes.

Molecular Mechanisms of WT1 Glomerulopathy
Fluorescent microscopy image of a kidney glomerulus showing cellular structures in multiple colors. Blue indicates cell nuclei, green outlines glomerular capillary loops, and red highlights podocyte markers. The image displays a dense cluster of cells with intricate green network patterns surrounded by blue-stained nuclei.

WT1, or wilms tumor 1, is a protein that plays an important role in kidney development and health, and mutations in WT1 can cause a spectrum of diseases, including wilms tumor, proteinuria and end-stage kidney disease. We are interested in better understanding the clinical spectrum of WT1-related disease as well as the mechanisms by which patient mutations may impact WT1 function.
