Hereditary hearing loss can be classified into two types: Syndromic Hearing Loss (SHL) and Non-Syndromic Hearing Loss (NSHL). NSHL is the most common form, accounting for about 70% of all genetic hearing loss cases.

Duchenne Muscular Dystrophy (DMD) is a rare X-linked recessive genetic disorder primarily caused by mutations in the DMDgene, leading to the absence of dystrophin, a protein crucial for maintaining the stability of muscle cell membranes.

Transthyretin Amyloidosis (ATTR) is a rare systemic disorder caused by the deposition of amyloid fibrils derived from misfolded transthyretin (TTR) protein.
