Total Knee Arthroplasty for Osteoarthritis in a Patient with Nail Patella Syndrome - A Case Report.

Int Med Case Rep J 2021 29;14:871-876. Epub 2021 Dec 29.

Orthopedic Department - Centro Hospitalar Universitário do Porto, Porto, Portugal.

Hereditary osteo-onychodysplasia (or nail patella syndrome) is a rare autosomal dominant disease defined by an association of severe characteristics, with a classic clinical tetrad of dysplasia of the fingernails, patellar hypoplasia or absence, presence of iliac horns, and deformities of the elbow, although renal, ocular and neurological involvement may also be present. The main orthopedic complaint of these patients is patellar instability associated with pain and functional limitation. Most of the literature regarding the treatment of NPS-related patellar problems, concerns pediatric population and there is no treatment algorithm defined for adult patients. Read More

Identification of limb-specific Lmx1b auto-regulatory modules with Nail-patella syndrome pathogenicity.

Nat Commun 2021 09 20;12(1):5533. Epub 2021 Sep 20.

Department of Pathology and Human Anatomy, Loma Linda University School of Medicine, Loma Linda, CA, USA.

LMX1B haploinsufficiency causes Nail-patella syndrome (NPS; MIM 161200), characterized by nail dysplasia, absent/hypoplastic patellae, chronic kidney disease, and glaucoma. Accordingly in mice, Lmx1b has been shown to play crucial roles in the development of the limb, kidney and eye. Although one functional allele of Lmx1b appears adequate for development, Lmx1b null mice display ventral-ventral distal limbs with abnormal kidney, eye and cerebellar development, more disruptive, but fully concordant with NPS.

A Novel LMX1B Variant Identified in a Patient Presenting with Severe Renal Involvement and Thin Glomerular Basement Membrane.

Nephron 2021 26;145(6):776-782. Epub 2021 Aug 26.

Department of Nephrology, Yokosuka Kyosai Hospital, Yokosuka, Japan.

We report a case of nail-patella syndrome (NPS) with unusual thinning of the glomerular basement membrane (GBM) associated with a novel heterozygous variant in the LMX1B gene. A 43-year-old female patient with a previous diagnosis of NPS, referred to our hospital for persistent proteinuria, underwent a renal biopsy, which revealed minor glomerular abnormalities. She underwent a second renal biopsy at the age of 56 owing to the presence of persistent proteinuria and decline in serum albumin, meeting the diagnostic criteria for nephrotic syndrome. Read More

Case Report: Corneal Leucoma as a Novel Clinical Presentation of Nail-Patella Syndrome in a 5-Year-Old Girl.

Front Pediatr 2021 14;9:638630. Epub 2021 Jun 14.

Nail-patella syndrome (NPS) is a rare autosomal-dominant disorder characterized by the classic tetrad of absent or hypoplastic finger and toe nails, absent or hypoplastic patella, skeletal deformities involving the elbow joints, and iliac horns. This disease is caused by heterozygous pathogenic variations in the gene, which encodes the LIM homeodomain transcription factor protein (LMX1B). We report a case of corneal leucoma and dysplasia prior to overt steroid-resistant nephrotic syndrome (SRNS) in a patient with NPS. Read More

LMX1B-associated nephropathy that showed myelin figures on electron microscopy.

CEN Case Rep 2021 11 2;10(4):588-591. Epub 2021 Jun 2.

Department of Nephrology, Tokyo Medical University Ibaraki Medical Center, 3-20-1 Chuo Ami, Inashiki, Ibaraki, 300-0395, Japan.

The mutation of LIM homeodomain transcription factor LMX1B gene leads to nail-patella syndrome (NPS), which is characterized by dysplastic nails, hypoplastic patellae, iliac horns and nephropathy. The characteristic renal histological finding of NPS nephropathy is irregular thickening of the glomerular basement membrane with patchy lucent areas, including deposits of bundles of type III collagen fibrils revealed by electron microscopy (EM). Fabry disease is a lysosomal storage disorder caused by a deficiency of α-galactosidase A activity, and the characteristic EM finding is a lamellated membrane structure (myelin figures). Read More

Dermatol Pract Concept 2020 Oct 26;10(4):e2020095. Epub 2020 Oct 26.

Dermatology Unit, University of Campania Luigi Vanvitelli, Naples, Italy.

Background: The skin is often seen as a world apart, but not rarely do cutaneous manifestations reveal signs of systemic disease.

Telmisartan alleviates collagen type III glomerulopathy: A case report with literature review.

Exp Ther Med 2020 Dec 5;20(6):140. Epub 2020 Oct 5.

Department of Nephrology, The Second Hospital of Jilin University, Changchun, Jilin 130041, P.R. China.

Collagen type III is commonly detected in the renal interstitium and vasculature; however, it is absent in healthy glomeruli. Deposition of collagen type III in the glomerular mesangium and capillary basement membranes may arise in two rare diseases, namely collagen type III glomerulopathy (CG) and nail patella syndrome. CG is a rare glomerular disease with no specific treatment, although supportive measures for control of hypertension and edema may help to relieve symptoms. Read More

Focal and segmental glomerulosclerosis (FSGS) is a histopathological pattern of injury. As such, it encompasses a wide variety of dissimilar entities with different pathophysiologic mechanisms. Although ultrastructural morphological characteristics can specifically diagnose certain diseases and genetic mutations can also be unravelled, this ideal situation is generally not available worldwide.
