Autosomal recessive spastic ataxia of Charlevoix Saguenay (ARSACS) is an early-onset, slowly progressive spastic ataxia associated with axonal-demyelinating polyneuropathy, hypermyelinated retinal fibers, and, sometimes, with an IQ in the lower normal range [1]. MRI studies typically show vermian, cervical, and dorsal spinal cord atrophy, and T2 and FLAIR linear hypointensities in the pons [2]. So far, over 70 mutations in SACS have been described, but the significant clinical variability amongst patients – especially in atypical cases described outside Quebec [1] – limits easy genotype– phenotype correlations. Here, we describe two unrelated ARSACS patients from central Italy carrying two novel mutations in SACS

Abstract
Autosomal recessive spastic ataxia of Charlevoix Saguenay (ARSACS) is an early-onset, slowly progressive spastic ataxia associated with axonal-demyelinating polyneuropathy, hypermyelinated retinal fibers, and, sometimes, with an IQ in the lower normal range [1]. MRI studies typically show vermian, cervical, and dorsal spinal cord atrophy, and T2 and FLAIR linear hypointensities in the pons [2]. So far, over 70 mutations in SACS have been described, but the significant clinical variability amongst patients – especially in atypical cases described outside Quebec [1] – limits easy genotype– phenotype correlations. Here, we describe two unrelated ARSACS patients from central Italy carrying two novel mutations in SACSI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
