Steroid-resistant nephrotic syndrome poses a significant clinical challenge. Its pathogenesis has not been fully elucidated. In recent years, numerous studies have shown that podocyte-specific gene mutations may play important roles in the development of steroid-resistant nephrotic syndrome. Among the identified genes mutated in podocytes include NPHS2, NPHS1, WT1, TRPC6, MDR1, PLCE1, LMX1B, and LAMB2. This review aims to summarize the characteristics of these mutated genes in podocytes. The putative role for these podocyte-specific mutated genes in the pathogenesis, diagnosis, treatment and prognosis of steroid-resistant nephrotic syndrome is also discussed.

Childhood idiopathic nephrotic syndrome is an important pediatric kidney disease associated with significant morbidities and even mortality. Several guidelines have been developed to standardize the terminology and patient care among the pediatric nephrology community. Since the publication of these guidelines, there have been major breakthroughs in the disease management and the understanding of underlying pathogenesis through multi-omics investigations, including the identification of anti-nephrin autoantibodies, genetic susceptibility loci, and the pathogenic role of B cell subsets.

Objectives: To determine incidence and risk factors for hypertension in childhood nephrotic syndrome.
Study Design: Using data from the Insight into Nephrotic Syndrome (INSIGHT) study, a prospective observational childhood nephrotic syndrome cohort from Toronto, Canada, we evaluated hypertension incidence and time-to-hypertension overall and stratified by 1) steroid-resistance or steroid-sensitivity, and 2) frequently-relapsing, steroid dependent, or infrequently-relapsing. Hypertension was defined as stage 1-2 hypertensive blood pressure on two consecutive visits or anti-hypertensive medication initiation.

Introduction: The profile of genetic and nongenetic factors associated with progression to kidney failure (KF) in steroid-resistant nephrotic syndrome (SRNS) is largely unknown in admixed populations.
Methods: A total of 101 pediatric patients with primary SRNS were genetically assessed targeting Mendelian causes and status with a 62-NS-gene panel or whole exome sequencing, as well as genetic ancestry. Variant pathogenicity was evaluated using the American College Medical of Genetics and Genomics (ACMG) criteria.

We report the case of a 49-year-old Chinese woman with nephrotic syndrome, characterized by normal kidney function but poor response to hormonal and immunosuppressive therapy, indicative of steroid-resistant nephrotic syndrome. Through renal biopsy, the patient was diagnosed as havingfocal segmental glomerulosclerosis (perihilar type), and subsequent whole-exome sequencing identified a pathogenic frameshift variant concerning the TBC domain of the gene. This patient represents the first late-onset Chinese female who was found to carry a novel, pathogenic variant in the gene .

PDSS1 mutations hamper Coenzyme Q10 biosynthesis and cause a rare multisystem mitochondrial disease characterized by diverse clinical features and limited treatment options. To date, renal involvement has been reported in only one patient. We report a new female patient with compound heterozygous PDSS1 mutations and the clinical outcome following a trial of Coenzyme Q10 therapy.
