A Novel Mutation in Aspartoacylase Gene; Canavan Disease
نویسندگان
چکیده
Objective Canavan disease (CD) is a type of vacuolating leukodystrophy with autosomal recessive inheritance. Aspartoacylase deficiency results in decrease of myelin biosynthesis, dysmyelination and brain edema. Although CD is a very common in Ashkenazi Jews patients, several cases have been reported from non-Jewish population. This report is based on a homozygous C.202G>A mutation in the ASPA gene identified from an Iranian patient. To our knowledge, this type of mutation has not been reported in non-Jewish population in the literature.

Canavan disease (CD) (OMIM 271900) is an autosomal recessive leucodystrophy characterised by swelling and spongy degeneration of the white matter of the brain. The biochemical marker for the disorder is increased level of N-acetylaspartic acid (NAA) in cerebrospinal fluid and urine owing to aspartoacylase (ASPA) deficiency. 2 The disease is caused by mutations in the gene encoding the enzyme as...

Introduction Canavan disease (CD) is a type of vacuolating leukodystrophy with autosomal recessive inheritance (1). This neurodegenerative disorder is caused by a defect in the aspartoacylase (ASPA) gene encoding the critical enzyme aspartoacylase, which has the role of hydrolyzing N-acetyl-L-aspartic acid (NAA) and providing the acetyl group to oligodendrocytes for myelin synthesis (2, 3). Asp...

Canavan disease (CD), an autosomal recessive neurodegenerative disorder, is caused by mutations in the aspartoacylase (ASPA) gene. In the present study, the ASPA gene was analyzed in 24 non-Jewish patients with CD from 23 unrelated families. Within this cohort, we found three large novel deletions of approximate 92, 56, and 12.13 kb in length, using both self-ligation of restriction endonucleas...

Canavan disease is a severe progressive leukodystrophy characterized by swelling and spongy degeneration of the white matter of the brain. It is an autosomal recessive disease found more frequently among Ashkenazi Jews. The clinical features are those of severe mental retardation with inability to gain developmental milestones. Hypotonia, head lag and macrocephaly are characteristic of Canavan ...
