  • Epilepsy and metalchromatic leukodystrophy:analysis of the clinical data and the gene mutations inafamily with late infantile metalchromatic leukodystrophy

    Objective To research the clinical characteristics and the arysulfatase A(ARSA) gene screening inafamily withametachromatic leukodystrophy and epilepsy child. Methods Clinical data were collected and ARSA gene were tested by PCR and Sanger sequencing in the pedigree. Results Two mutations in exon 2 of ARSA gene was identified in the proband includingaknown heterozygous missense mutation c.293C>T which was also found in his mother andanovel frameshift mutation c.302de1G. None of them was found in the proband’s brother. Conclusion The intractable epilepsy of the proband was related to his metachromatic leukodystrophy. Andanew frameshift mutation c.302delG was found in his ARSA gene, which haven’t reported around the world yet. Combined with the patient’s typical late infantile presentation, we speculated that the frameshift mutation c.302delG may be the cause of MLD.
