Özet

Pathogenic variants of sacsin (SACS) gene cause autosomal recessive Spastic Ataxia of Charlevoix-Saguenay (ARSACS). It is a hereditary neurological disorder manifested with gait ataxia, intentional tremor, lower limb pyramidal signs and pes cavus. It was originally described in the late 1970s and has a high prevalence in northeastern Quebec, Canada. Here, we present for the first time a new SACS frameshift variant in two Turkish siblings. We detected a new homozygous frameshift variant of the SACS gene in the Turkish siblings diagnosed with ARSACS for the first time.
