XX. SCF LAYMAN’S SUMMARY
Zellweger Syndrome is the most severe form of a group of disorders called Zellweger Spectrum Disorders. It occurs when cells cannot properly build peroxisomes, tiny structures that process certain fats and detoxify harmful substances. Without functioning peroxisomes, toxic compounds accumulate while essential cellular products become deficient. This causes severe problems affecting the brain, liver, kidneys, vision, hearing, and overall development. SCF interprets Zellweger Syndrome as a cellular infrastructure-construction disorder in which a critical metabolic organelle fails to form, leading to widespread metabolic and developmental collapse.
