: This study reveals the first evidence of the involvement of single nucleotide polymorphisms around the connective tissue growth factor (<i>CTGF</i>) gene in relapsing–remitting multiple sclerosis (RRMS) risk and disability progression. The downstream variant rs9399005 was associated with RRMS and a higher rate of disability progression reflected by a higher Multiple Sclerosis Severity Score (MSSS). Furthermore, MSSS was significantly lower in patients with at least one rs12526196C allele than in the corresponding patients with the wild-type genotype. These data indicate a role for the variants in the region flanking <i>CTGF</i> gene in RRMS risk and disability progression.
