Abstract

Background: Substantial efforts have been deployed in the past decade to identify the genetic causes of amyotrophic lateral sclerosis (ALS), and we hypothesized here that mutations in . SORT1 or aberrant . SORT1 splicing reduce progranulin level and promote neurodegeneration. Methods: We sequenced the coding exons of . SORT1 in a cohort of 112 unrelated individuals with familial ALS. We also tested for aberrant . SORT1 splicing by RT-PCR using RNA samples from cell lines expressing six different ALS-associated . TARDBP mutations. Results: We identified one unique missense and two unique silent mutations in our cohort. None are predicted to have functional effects. No aberrant . SORT1 splicing event was observed. Conclusions: SORT1 mutations are not a common cause of familial ALS, and the influence of . TARDBP mutations on . SORT1 splicing still needs to be clarified.
