Two novel aspartoacylase gene (ASPA) missense mutations specific to Norwegian and Swedish patients with Canavan disease

List of primers

Primer name Sequence Derived from GenBank accession number
To allow the discrimination between alleles D114 and 114Y (340G→T) the primers pCANmF and pCANmR were modified in the following way. For pCANmF the nine nucleotides at the 5` end are derived from the 3` splice acceptor of intron 1.4 In order to create an internal SnaBI control restriction site nucleotides C21, A22, and A24 (in bold, numbered from the 5` end) were replaced with A, C, and T (underlined), respectively. For pCANmR, nucleotides A25 and G27 were replaced with T and C (underlined), respectively. These replacements allowed SnaBI digestion of the mutant 114Y allele while leaving the D114 allele resistant.
