MEGALENCEPHALIC LEUKOENCEPHALOPATHY WITH SUBCORTICAL CYSTS WITH HOMOZYGOUS MUTATION (C.448DELC, P.LEU150 SER FSX11) ON EXON 6 OF MLC1 GENE.

MLC or Van der Knaap disease is a rare entity, a rare and genetically heterogeneous cerebral white matter disease. It is characterized by the presence of macrocephaly, epilepsy and a slowly progressive spastic cerebellar syndrome. It is an autosomal recessive disease caused from mutations of MLC1 gene. In the current case report, a case with MLC who had a homozygous mutation (c.448delC, p.Leul50 ser fsX11) on exon 6 of MLC1 gene is presented.
