Abstract

Insights

Familial membranous nephropathy (MN) linked to phospholipase A2 receptor (PLA2R) is rare. Genetic factors, specifically HLA-DRB1 alleles, appear to predispose individuals to PLA2R-related MN and co-occurring anti-GBM disease.

Area of Science:

  • Nephrology
  • Genetics
  • Immunology

Background:

  • Membranous nephropathy (MN) is an autoimmune kidney disease often associated with phospholipase A2 receptor (PLA2R) and human leukocyte antigen (HLA) genes.
  • Familial cases of PLA2R-related MN are uncommon, and the link with anti-glomerular basement membrane (anti-GBM) disease requires further mechanistic understanding.

Observation:

  • Two siblings were diagnosed with pathology-confirmed PLA2R-related MN within a year.
  • One sibling also developed anti-GBM disease.
  • High-resolution HLA typing revealed identical alleles (DRB1*15:01/*03:01) in both siblings.

Findings:

  • This familial case supports a genetic predisposition to PLA2R-related MN.
  • Specific HLA alleles, DRB1*15:01 and DRB1*03:01, are implicated in the development of PLA2R-related MN in the Han Chinese population.
  • The co-occurrence of MN and anti-GBM disease may be partly linked to the susceptible HLA allele DRB1*15:01.

Implications:

  • Identifies specific HLA alleles as potential genetic risk factors for PLA2R-related MN.
  • Suggests a shared genetic susceptibility between PLA2R-related MN and anti-GBM disease.
  • Highlights the importance of genetic screening in familial cases of nephropathy.

Nephrotic Syndrome I : Introduction01:24

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Renal Corpuscle01:20

Renal Corpuscle

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

Nephrotic Syndrome II : Assessment and Medical Management

IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

Nephrons01:10

Nephrons

The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

Acute Kidney Injury II: Pathophysiology

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...
