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.
Pathophysiology
Physiology
- GLA gene codes information for the alpha-galactosidase enzyme.
- The normal function of the alpha-galactosidase enzyme is to breakdown globotriaosylceramide (also abbreviated as Gb3, GL-3, or ceramide trihexoside) into glucocerebroside in lysosomes.
- Gb3 is produced in the catabolism pathway of Globoside, an essential glycosphingolipid in the cell membrane (RBCs and Kidney), that is mainly metabolized in the lysosome of the spleen, liver , and bone marrow.[1]
Pathogenesis
- Fabry disease is caused by a deficiency of alpha-galactosidase.
- Mutations to the GLA gene encoding α-GAL may result in a complete loss of function of the enzyme.
- Alpha-galactosidase is a lysosomal protein responsible for breaking down globotriaosylceramide(Gb3) a fatty substance stored in various types of cardiac and renal cells.[2]
- Improper catabolism causes globotriaosylceramide (Gb3) to accumulate in cells lining blood vessels in the skin, kidney, heart, and nervous system. As a result, signs, and symptoms of Fabry diseasseven begin to manifest.[3]
- Accumulation of globotriaosylceramide (Gb3) in different tissues leads to cellular death, compromised energy metabolism, small vessel injury, potassium-calcium channel dysfunction in the endothelial cells, oxidative stress,impaired autophagosome maturation, tissue ischemia, irreversible cardiac and renal tissue fibrosis.[4]
Genetics
- Fabry's disease follows an X-linked inheritance pattern.
- Since it is inherited in an X-linked pattern, males are homozygous and pass the disease to all daughters but no sons.
- Females are heterozygous with 50% chance of passing the mutated gene to both daughters and sons.[5]
- Skewed nonrandom X chromosome inactivation may cause paradoxical nature of the disease that is seen in females,; they have a varied presentation from being asymptomatic to having very severe symptoms and having a presentation similar to that seen in males with the classical type.[6]
- Gene function: GLA gene encodes information for alpha-Gal-A.
- Gene location: GLA has its locus located on the Longarm of chromosome X in position Xq22. It has seven exons distributed over 1290 base pairs of coding part. [7][8]
- Demonstrates extensive allelic heterogeneity but no genetic locus heterogeneity.[9]
- 585 mutations have so far been recorded for Fabry's disease.[10]
- Mutations demonstrated include Missense, Non-sense point mutations,splicing mutations, small deletion/Insertion, and large deletions.[11]
Gross pathology
- The most important characteristics of Fabry's disease on gross pathology are:
- Kidney
- Kidney enlargement
- Renal cysts of cortical and parapelvic
- Decreased cortical thickness[12]
- Heart
- Four chamber cardiomegaly( frequently LVH with interventricular septum hypertrophy)[13]
- Eye
- Conjunctiva
- Ampullary and saccular aneurysms of small venules
- Thrombosis[14]
- Retina
- Segmental dilatation and tortuosity of venules and arteries
- Whorl-like corneal dystrophic pattern[15]
- Conjunctiva
- Nervous system
- Central nervous system
- White matter lesion [16]
- Central nervous system
- Kidney
Microscopic pathology
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.
