The c.-265G>A GLA gene promoter variant causes Fabry disease: The hidden culprit identified.

Here, we report the identification and functional characterization of a novel GLA variant, not detectable by routine molecular tests, in a family with FD suspicion.

Fabry Disease Nephropathy: Histological Changes With Nonclassical Mutations and Genetic Variants of Unknown Significance.

Rationale & Objective: Fabry disease (FD) is an X-linked genetic disorder that causes lysosomal storage of glycosphingolipids, primarily globotriaosylceramide (Gb3) and its derivative globotriaosylsphingosine (lyso-Gb3), with multiorgan dysfunction including chronic kidney disease. Affected individuals may be carriers of gene variants that are of uncertain significance (GVUS). We describe kidney pathology at the early stages of FD-related kidney disease to gain insights into its association with GVUS and sex.

[IgA nephropathy and granulomatosis with polyangiitis-overlap: a rare coexistence of two glomerular nephropathies with remission after steroids and rituximab].

Granulomatosis with polyangiitis (GPA) is an ANCA-positive systemic vasculitis that mainly involves lungs and kidneys. This condition rarely overlaps with other glomerulonephritides. A 42-year-old man with constitutional symptoms and haemophtoe was admitted to the Infectious Diseases department, where he was subjected to fibrobronchoscopy with BAL (broncho-alveolar lavage) and lung transbronchial biopsy that showed histological signs of vasculitis.
