Novel exon 3B proteolipid protein gene mutation causing late-onset spastic paraplegia type 2 with variable penetrance in female family members.

Abstract excerpt

Spastic paraplegia type 2 (SPG2) is allelic to Pelizaeus-Merzbacher disease (PMD), with both conditions resulting from mutations in the proteolipid protein gene (PLP). We report an SPG2 family in which 3 male members and a heterozygous female member were affected with spastic paraplegia characterized by relatively late onset and mild clinical manifestations. A unique H147Y mutation in exon 3B of the PLP altering...
