Role of GM-NM-1(olf) in Familial and Sporadic Adult-Onset Primary Dystonia


ABSTRACT: Gene expression studies were performed to identify pathways possibly dysregulated by mutant in the gene GM-NM-1(olf). These experiments employed RNA derived from lymphoblastoid cell lines established for 4 affected carriers and 4 non-carriers. In comparison to endogenous control and other dystonia-associated genes, GNAL was expressed at relatively low levels in lymphoblastoid cell lines.

The vast majority of patients with primary dystonia are adults with focal or segmental distribution of involuntary movements. Although ~10% of probands have at least one first- or second-degree relative to dystonia, large families suited for linkage analysis are exceptional. After excluding mutations in known primary dystonia genes (TOR1A, THAP1 and CIZ1), whole-exome sequencing identified a GNAL missense mutation (c.682G>T, p.V228F) in an African-American pedigree with clinical phenotypes that  ...[more]
