Abstract

Abstract

En 中文
• We established the first patient-specific, compound heterozygous TWNK mutant mouse model of Perrault syndrome (PS). • This model recapitulates key clinical features of PS: hearing loss, motor deficits, and peripheral neuropathy. • Mutant mice show mitochondrial dysfunction with reduced mtDNA copy number and ATP levels. • This mice model enables future blinded therapeutic studies under controlled conditions.
