BackgroundStudies have identified mutations in >50 genes that can lead to monogenic steroid-resistant nephrotic syndrome (SRNS). The NUP160 gene, which encodes one of the protein components of the nuclear pore complex nucleoporin 160 kD (Nup160), is expressed in both human and mouse kidney cells. Knockdown of NUP160 impairs mouse podocytes in cell culture. Recently, siblings with SRNS and proteinuria in a nonconsanguineous family were found to carry compound-heterozygous mutations in NUP160.MethodsWe identified NUP160 mutations by whole-exome and Sanger sequencing of genomic DNA from a young girl with familial SRNS and FSGS who did not carry mutations in other genes known to be associated with SRNS. We performed in vivo functional validation studies on the NUP160 mutations using a Drosophila model.ResultsWe identified two compound-heterozygous NUP160 mutations, NUP160R1173× and NUP160E803K. We showed that silencing of Drosophila NUP160 specifically in nephrocytes (fly renal cells) led to functional abnormalities, reduced cell size and nuclear volume, and disorganized nuclear membrane structure. These defects were completely rescued by expression of the wild-type human NUP160 gene in nephrocytes. By contrast, expression of the NUP160 mutant allele NUP160R1173× completely failed to rescue nephrocyte phenotypes, and mutant allele NUP160E803K rescued only nuclear pore complex and nuclear lamin localization defects.ConclusionsMutations in NUP160 are implicated in SRNS. Our findings indicate that NUP160 should be included in the SRNS diagnostic gene panel to identify additional patients with SRNS and homozygous or compound-heterozygous NUP160 mutations and further strengthen the evidence that NUP160 mutations can cause SRNS.

Chronic kidney disease of unknown etiology (CKDu) has been a problem in renal practice as indefinite diagnosis may lead to inappropriate management. Here, we report a 54-year-old father diagnosed with CKDu at 33 years old and his 8-year-old son with steroid-resistant nephrotic syndrome. Using whole-exome sequencing, both were found to be heterozygous for c.737G>A (p.Arg246Gln) in LMX1B. The diagnosis of LMX1B-associated nephropathy has led to changes in the treatment plan with appropriate genetic counseling. The previously reported cases with this particular mutation were also reviewed. Most children with LMX1B-associated nephropathy had nonnephrotic proteinuria with normal renal function. Interestingly, our pediatric case presented with steroid-resistant nephrotic syndrome at 8 years old and progressed to ESRD requiring peritoneal dialysis at the age of 15 years. Our report emphasized the need of genetic testing in CKDu for definite diagnosis leading to precise management.

Описан клинический случай пациент с нефротическим синдромом, стероид резистентный вариант, с артериальной гипертензией, осложненный полисерозитом (гидроторакс, асцит, плеврит). Пациент поступил в клинику в состоянии средней степени тяжести, с массивными отеками, полисерозитом, артериальной гипертензией и выраженным нефротическим синдромом. Диагноз: Гломерулярная болезнь. Нефротический синдром, стероид резистентный вариант. Функция почек снижена (СКФ- 84мл/мин по Шварцу). Двухсторонний экссудативный плеврит. Гидроторакс. Полисерозит (в рамках нефротического синдрома) был установлен на основании выраженного нефротического синдрома. Пациенту была проведена патогенетическая терапия. Отмечено улучшение состояния больного, в виде снижения отеков, нормализаций артериального давления, что в свою очередь поспособствовало сохранению и улучшению качества жизни пациента. A clinical case of a patient with nephrotic syndrome, steroidresistant variant, with arterial hypertension complicated by polyserositis (hydrothorax, ascites, pleurisy) is described. The patient was admitted to the clinic in a state of moderate severity, with massive edema, polyserositis, arterial hypertension, and severe nephrotic syndrome. Diagnosis: Glomerular disease. Nephrotic syndrome, steroidresistant variant. The kidney function is reduced (GFR - 84 ml/min according to Schwartz). Bilateral exudative pleurisy. Hydrothorax. Polyserositis (within the framework of nephrotic syndrome) was established based on the severe nephrotic syndrome. The patient underwent pathogenetic therapy. An improvement in the patient's condition was noted, in the form of a decrease in edema, normalization of blood pressure, which in turn contributed to the preservation and improvement of the patient's quality of life.
