Early life and education

Hildebrandt received his M.D. degree from Heidelberg University (Germany), obtained his pediatrics and nephrology subspecialty training at Marburg University Children's Hospital, and was a postdoctoral research fellow in nephrology at Yale School of Medicine (Peter Aronson & Peter Igarashi).[ citation needed ]

Research

Friedhelm Hildebrandt identified and functionally characterized multiple kidney diseases caused by single-genes (Mendelian) including nephrotic syndrome, cystic renal ciliopathies, [4] and congenital anomalies of the kidney [5]

Hildebrandt was elected to the American National Academy of Medicine in 2015, [6] Leopoldina in 2007, [7] and to the Association of American Physicians in 2005. [8] He is a recipient of the Homer Smith Award of the American Society of Nephrology (2014), [9] the Alfred R. Newton Award of the International Society of Nephrology (ISN) (2017), [10] and the E. Mead Johnson Award [11] from the Society for Pediatric Research (2004).

Hildebrandt’s group has identified over 80 novel causative genes of the 240 genes that are currently known to cause chronic kidney disease, if mutated. [12] His laboratory delineated the related disease mechanisms by generating animal models of human kidney disease in mice, zebrafish, C. elegans, and Drosophila as well in cell-based systems. He demonstrated that in a very high percentage of cases with early-onset chronic kidney disease a single-gene cause may be identified. [13] [14] Link to pertinent publications. [12]

<span class="mw-page-title-main">Nephrology</span> Medical study concerned with the kidneys

Nephrology is a specialty for both adult internal medicine and pediatric medicine that concerns the study of the kidneys, specifically normal kidney function and kidney disease, the preservation of kidney health, and the treatment of kidney disease, from diet and medication to renal replacement therapy. The word "renal" is an adjective meaning "relating to the kidneys", and its roots are French or late Latin. Whereas according to some opinions, "renal" and "nephro" should be replaced with "kidney" in scientific writings such as "kidney medicine" or "kidney replacement therapy", other experts have advocated preserving the use of renal and nephro as appropriate including in "nephrology" and "renal replacement therapy", respectively.

<span class="mw-page-title-main">Kidney disease</span> Damage to or disease of a kidney

Kidney disease, or renal disease, technically referred to as nephropathy, is damage to or disease of a kidney. Nephritis is an inflammatory kidney disease and has several types according to the location of the inflammation. Inflammation can be diagnosed by blood tests. Nephrosis is non-inflammatory kidney disease. Nephritis and nephrosis can give rise to nephritic syndrome and nephrotic syndrome respectively. Kidney disease usually causes a loss of kidney function to some degree and can result in kidney failure, the complete loss of kidney function. Kidney failure is known as the end-stage of kidney disease, where dialysis or a kidney transplant is the only treatment option.

<span class="mw-page-title-main">Podocyte</span> Type of kidney cell

Podocytes are cells in Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus. Podocytes make up the epithelial lining of Bowman's capsule, the third layer through which filtration of blood takes place. Bowman's capsule filters the blood, retaining large molecules such as proteins while smaller molecules such as water, salts, and sugars are filtered as the first step in the formation of urine. Although various viscera have epithelial layers, the name visceral epithelial cells usually refers specifically to podocytes, which are specialized epithelial cells that reside in the visceral layer of the capsule.

<span class="mw-page-title-main">Gitelman syndrome</span> Medical condition

Gitelman syndrome (GS) is an autosomal recessive kidney tubule disorder characterized by low blood levels of potassium and magnesium, decreased excretion of calcium in the urine, and elevated blood pH. It is the most frequent hereditary salt-losing tubulopathy. Gitelman syndrome is caused by disease-causing variants on both alleles of the SLC12A3 gene. The SLC12A3 gene encodes the thiazide-sensitive sodium-chloride cotransporter, which can be found in the distal convoluted tubule of the kidney.

Galloway–Mowat syndrome is a very rare autosomal recessive genetic disorder, consisting of a variety of features including hiatal hernia, microcephaly and nephrotic syndrome.

Podocin is a protein component of the filtration slits of podocytes. Glomerular capillary endothelial cells, the glomerular basement membrane and the filtration slits function as the filtration barrier of the kidney glomerulus. Mutations in the podocin gene NPHS2 can cause nephrotic syndrome, such as focal segmental glomerulosclerosis (FSGS) or minimal change disease (MCD). Symptoms may develop in the first few months of life or later in childhood.

<span class="mw-page-title-main">Nephronophthisis</span> Medical condition

Nephronophthisis is a genetic disorder of the kidneys which affects children. It is classified as a medullary cystic kidney disease. The disorder is inherited in an autosomal recessive fashion and, although rare, is the most common genetic cause of childhood kidney failure. It is a form of ciliopathy. Its incidence has been estimated to be 0.9 cases per million people in the United States, and 1 in 50,000 births in Canada.

Primary hyperoxaluria is a rare condition, resulting in increased excretion of oxalate, with oxalate stones being common.

AA amyloidosis is a form of amyloidosis, a disease characterized by the abnormal deposition of fibers of insoluble protein in the extracellular space of various tissues and organs. In AA amyloidosis, the deposited protein is serum amyloid A protein (SAA), an acute-phase protein which is normally soluble and whose plasma concentration is highest during inflammation.

<span class="mw-page-title-main">Ciliopathy</span> Genetic disease resulting in abnormal formation or function of cilia

A ciliopathy is any genetic disorder that affects the cellular cilia or the cilia anchoring structures, the basal bodies, or ciliary function. Primary cilia are important in guiding the process of development, so abnormal ciliary function while an embryo is developing can lead to a set of malformations that can occur regardless of the particular genetic problem. The similarity of the clinical features of these developmental disorders means that they form a recognizable cluster of syndromes, loosely attributed to abnormal ciliary function and hence called ciliopathies. Regardless of the actual genetic cause, it is clustering of a set of characteristic physiological features which define whether a syndrome is a ciliopathy.

<span class="mw-page-title-main">Polycystic kidney disease</span> Congenital disorder of urinary system

Polycystic kidney disease is a genetic disorder in which the renal tubules become structurally abnormal, resulting in the development and growth of multiple cysts within the kidney. These cysts may begin to develop in utero, in infancy, in childhood, or in adulthood. Cysts are non-functioning tubules filled with fluid pumped into them, which range in size from microscopic to enormous, crushing adjacent normal tubules and eventually rendering them non-functional as well.

Glomerulonephrosis is a non-inflammatory disease of the kidney (nephrosis) presenting primarily in the glomerulus as nephrotic syndrome. The nephron is the functional unit of the kidney and it contains the glomerulus, which acts as a filter for blood to retain proteins and blood lipids. Damage to these filtration units results in important blood contents being released as waste in urine. This disease can be characterized by symptoms such as fatigue, swelling, and foamy urine, and can lead to chronic kidney disease and ultimately end-stage renal disease, as well as cardiovascular diseases. Glomerulonephrosis can present as either primary glomerulonephrosis or secondary glomerulonephrosis.
