WebDNA sequence analysis revealed the infant to be compound heterozygous with two mutations, c.738dupG in exon 8 of GSS gene resulting in p.S247fs and a repetitive sequence in exon 3 of GSS gene. Prion diseases, also called transmissible spongiform encephalopathies (TSEs), are neurodegenerative diseases of the brain thought to be caused by a protein that converts to an abnormal form called a prion. GSS is a very rare TSE, making its genetic origin nearly impossible to determine. It is also challenging to find any patients with GSS, as the disease tends to be underreported, due to its clinical similarity to other diseases, and has been found in only a few c…
