a rare condition and a rare mode of genetic transmission INTRODUCTION Alport syndrome (AS) is a rare abnormality of glomerular basement membrane caused by mutations in several different genes‚ all of which encode particular forms of type IV collagen‚ a major component of basement membrane. It is characterized by chronic renal failure leading to end-stage renal disease (ESRD) and is often associated with sensorineural deafness (Kanski 2003).

Due to the intervertebral disc specific structure and the interactions between nucleus pulposus and annulus fibrosus‚ it is capable to resist high compressive loads and provide spinal mobility (Tang‚ Liu‚ & Zhang‚ 2014). The nucleus pulpous is capable to endure high compressive forces because of its high water content‚ low permeability and osmotic properties (Galbusera et al.‚ 2014). It works by distributing hydraulic pressure in multiple directions within each intervertebral disc under compressive
