Background: Prion diseases are a group of neurodegenerative diseases associated with prion protein. The disease can be caused by mutations in the PRNP gene, the gene that encodes prion protein. An octapeptide repeat on the N-terminus of prion protein plays an important role in normal intercellular function of prion protein.

Background: Sporadic Creutzfeldt-Jakob disease (sCJD) is one of common causes of rapidly progressive dementia worldwide. However, because of the variety of its clinical presentations that mimic other cognitive disorders, the certain diagnosis in public hospitals is still limited. Therefore, this study provides more information about disease manifestations and clinical courses of probable sCJD cases in Thailand.

The human prion protein gene (PRNP) consists of two common alleles that encode either methionine or valine residues at codon 129. Polymorphism at codon 129 of the prion protein (PRNP) gene is closely associated with genetic variations and susceptibility to specific variants of prion diseases. The presence of these different alleles, known as the PRNP codon 129 polymorphism, plays a significant role in disease susceptibility and progression.

Corneal graft (keratoplasty) is the most common allograft in the world, but the imbalance between the number of donors and the number of patients waiting for transplants is abysmal on a global scale and varies enormously from one country to another. The risk of transmission of systemic diseases from donor to recipient is demonstrably low. In over 50 years and an estimated 2.
