What molecular mechanisms determine why VCP mutations cause isolated FTD versus multisystem IBMPFD?

OPEN

This family shows pure bvFTD without muscle or bone involvement despite having VCP mutations that typically cause multisystem disease. The mechanistic basis for this phenotypic selectivity is unknown and critical for understanding VCP pathogenesis.
