Final answer:
The etiologies of focal segmental glomerulosclerosis disease include acute glomerulonephritis, post-renal causes, genetic mutations, and idiopathic juxtafoveal retinal telangiectasia.
Step-by-step explanation:
Etiologies of Focal Segmental Glomerulosclerosis Disease:
- Acute glomerulonephritis due to various causes like anti-glomerular basement membrane disease/Goodpasture's syndrome, Wegener’s granulomatosis, or acute lupus nephritis
- Post-renal causes due to obstructive factors in the urinary tract
- Genetic mutations that prevent the synthesis of critical proteins
- Idiopathic juxtafoveal retinal telangiectasia (dilated, twisted blood vessels in the retina)
