==Overview==
==Overview==
[[Genes]] involved in the pathogenesis of [[Fabry's disease]] include the [[GLA gene]], which codes the important enzyme of [[alpha-galactosidase]]. The absence or lack of this enzyme causes [[Gb3]] accumulation in different organs. The main pathological finding is detection of these inclusion in different cells with [[Electron microscopy|electron]] microscopies.

====Physiology====


*[[GLA|GLA gene]] codes information for the enzyme [[Alpha-galactosidase|alpha- galactosidase]].
*[[GLA|GLA gene]] codes information for the [[Alpha-galactosidase|alpha-galactosidase]] enzyme.
*Normal function of the enzyme [[alpha-galactosidase]] is to breakdown [[Globotriaosylceramide 3-beta-N-acetylgalactosaminyltransferase|globotriaosylceramide]] (also abbreviated as [[Globotriaosylceramide 3-beta-N-acetylgalactosaminyltransferase|Gb3, GL-3, or ceramide trihexoside]]) into [[glucocerebroside]] in [[lysosomes]] that serve as recycling centres.

*[[Gb3]] is produced in the catabolism pathway of [[Globoside]], an essential [[glycophingolipids|glycosphingolipid]] in the cell membrane ([[RBC]]s and Kidney), that is mainly metabolized in the [[lysosome]] of the [[spleen]], [[liver]] , and [[bone marrow]].<ref name="pmid345762505">{{cite journal| author=Tuttolomondo A, Simonetta I, Riolo R, Todaro F, Di Chiara T, Miceli S | display-authors=etal| title=Pathogenesis and Molecular Mechanisms of Anderson-Fabry Disease and Possible New Molecular Addressed Therapeutic Strategies. | journal=Int J Mol Sci | year= 2021 | volume= 22 | issue= 18 | pages=  | pmid=34576250 | doi=10.3390/ijms221810088 | pmc=8465525 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=34576250  }}</ref>

On histopathological analysis, these findings are characteristic of [[Fabry's disease]]:


* light microscopy is not as specific in confirming FD as electron microscopy and thus is only done when electron microscopy is unavailable. Lipid staining of a kidney biopsy may demonstrate storage cells within the glomeruli, which proves of little significance.  
======General======
* Ultrastructural analysis of the heart and kidney biopsies can reveal lysosomal storage in the endomyocardial and certain renal tubular cells respectively. The ultrastructural appearance of these inclusions is whorled layers of alternating dense and pale material also called zebra bodies.  
On microscopic histopathological analysis, tissue deposition of glycosphingolipids crystalline is a characteristic finding of [[Fabry's disease]].

Overview

Genes involved in the pathogenesis of Fabry's disease include the GLA gene, which codes the important enzyme of alpha-galactosidase. The absence or lack of this enzyme causes Gb3 accumulation in different organs. The main pathological finding is detection of these inclusion in different cells with electron microscopies.

General

On microscopic histopathological analysis, tissue deposition of glycosphingolipids crystalline is a characteristic finding of Fabry's disease.

  • Glycosphingolipid inclusions morphology: coarsely lamellated appearance, maybe round with onion-skin likes structure (Myelin figures), or dense unstructured layer (Zebra bodies), some can be dark electrodense and amorphous especially in endothelial and mesangial cells.[17]
  • Electron Microscopy: The most accurate method for detection of glycosphingolipids depositions. preserved whole glycosphingolipids during the preparation process.[18]
  • Light microscopy is not as specific in confirming FD as electron microscopy and thus is only done when electron microscopy is unavailable.

(swollen appearance)

Characteristic but not pathognomonic
Jones methenamine silver (JMS) staining granular and argyrophilic inclusions due to the residual carbohydrate part of glycosphingolipids
Methacrylate-embedded sections[21] Lipid-soluble dye glycosphingolipids inclusions not routine
Frozen section[22] Allows preservation but may lose dome details
Epon-embedded sections[23] Toluidine blue dark blue and dark gray round spiral inclusions detect entire glycosphingolipids
