We identified a novel c.1556A>G transition in exon 12 of the HEXB gene associated with chronic Sandhoff's disease, changing a conserved aspartic acid to glycine at position 494 of the Hex beta-subunit; moreover, RT-PCR showed aberrant exon 12 skipping, causing a frame-shift and premature stop codon, consequent to the disruption of an exonic splicing enhancer motif by the mutation. These data suggest that the c.1556 A>G transition would affect both HEXB mRNA processing and biochemical properties of the beta-subunit.
