Genotype-phenotype Correlation in Pelizaeus Merzbacher Disease and Pelizaeus Merzbacher-like Disease

Abstract

Objective: Among the hypomyelinating diseases of childhood, Pellizeus Merzhachcr disease (PMD) is caused by X-linked proteolipid protein (PLP) gene mutations, whereas patients without mutations of PLP gene-called Pelizaues Merzbacher-like disease (PMLD) have recessive gap junction protein alpha 12 (gap junction alpha-12/gap junction gamma-2) gene mutations. The aim of this study was to evaluate clinical severity and progression in time in patients with PMD and PMLD.
