Explanation / Answer

Interaction of polar side chains of protein sequence leads to formation of a tightly packed hydrophobic core. This core is stabilised by a large number of hydrogen bond. When a mutation occur it destabilizes the protein core and weakens disulphide bridge leading to mis folding.
