چکیده

A molecular analysis of the arylsulphatase A gene was performed on 26 unrelated, Italian, late infantile metachromatic leucodystrophy patients. The frequency of the common disease causing mutations 609A and 2381T was 28.8% and 1.9% respectively. Pseudodeficiency allele frequency in patients was found to be 13.5% and a frequency of 10.1% was found in 89 unaffected normal controls. The frequency of the 609A mutation in Italian late infantile patients is lower than in late infantile patients from northern Europe, suggesting a higher frequency of different sporadic mutations in the Italian population. A cooperative in cis effect in phenotype determination involving arylsulphatase A mutations and the eventual background of the pseudodeficiency allele is proposed.

Metachromatic leucodystrophy in three families from Nova Scotia, Canada: a recurring mutation in the arylsulphatase A gene.

Metachromatic leucodystrophy (MLD) is a lysosomal storage disease resulting from a deficiency of arylsulphatase A. We have identified a child with infantile onset MLD who is homozygous for an A212V mutation, a mutation previously reported but not further characterised. We have introduced this mutation into an arylsulphatase A expression vector by site directed mutagenesis. Transient expression ...

Received 15 March 1995 Revised version accepted for publication 24 May 1995 Abstract Metachromatic leucodystrophy (MLD) is an autosomal recessive lysosomal storage disease resulting from a severe deficiency of arylsulphatase A. The arylsulphatase A gene is located on chromosome 22 at q13.3. An MLD patient is described who carries a common splicing mutation ("I" allele) and a de novo ring 22 del...

The arylsulphatase A gene and molecular genetics of metachromatic leucodystrophy.

The lysosomal storage disorders share one common characteristic: the accumulation of a particular substrate inside the lysosome. Each disorder in this group is caused either by the deficiency of a lysosomal enzyme responsible for one step of the degradation pathway of a substrate, lack of a transporter involved in the movement of a small molecule across the lysosomal membrane, or absence of a l...

Peripheral neuropathy detected on electrophysiological study as first manifestation of metachromatic leucodystrophy in infancy.

A case of infantile metachromatic leucodystrophy is described in which symptoms started at 1 year of age with weakness and hypotonus in the lower extremities. The electrophysiological status was typical of a polyneuropathy, showing fibrillation and a reduction of the nerve conduction velocity to 30 percent of the average for normal children of the same age. Clinical signs of a central lesion an...
