Understanding Hereditary Spastic Paraplegia Type 15
What is SPG15?
Hereditary Spastic Paraplegia Type 15 (SPG15) is a rare, neurodegenerative disease caused by mutations in the ZFYVE26 gene. The autosomal recessive genetic disorder is characterized by cognitive impairments, muscle stiffness, and paralysis of the limbs. Signs of SPG15 often become apparent in adolescence, and as the condition progresses many patients experience severe cognitive and physical decline.
What is the prevalence of SPG15?
SPG15 is ultra-rare, occurring in less than 100 patients globally. Unfortunately, as with many ultra-rare conditions, research is sparse – with limited data, geographic challenges, lack of advocacy, and research funding, etc. When research resources are not allocated and data cannot be connected, opportunities to advance discovery is limited.
