REEP4 variant analysis in blepharospasm and other neurological disorders.

ABSTRACT:

Introduction

In preceding work, a deleterious REEP4 variant [GRCh38/hg38, NC_000008.11:g.22140245G>A, NM_025232.4:c.109C>T, p.Arg37Trp] was found to co-segregate with blepharospasm (BSP) in a large African-American pedigree. Other REEP4 variants have been reported in genetic screening studies of dystonia. The REEP4 paralogs, REEP1 and REEP2, are associated with spastic paraplegia. The causal contributions of REEP4 variants to dystonia and other neurological disorders remains indecisive.

Methods

Sanger sequencing was used to screen subjects (N = 307) with BSP and BSP-plus dystonia affecting additional anatomical segments (BSP+) phenotypes for variants in REEP4. In silico tools were used to examine the deleteriousness of
