Mouse Lysosomal acid lipase/cholesteryl ester hydrolase (LIPA) ELISA Kit

Lysosomal acid lipase (LIPA, or LAL), otherwise known as acid cholesteryl ester hydrolase, is coded for by a gene (LIPA) on chromosome 10. Two major disorders, the severe infantile-onset Wolman disease and the milder late-onset cholesteryl ester storage disease (CESD), are seemingly caused by mutations in different parts of the LIPA gene. Aslanidis et al. (1996) provided evidence that a strikingly more severe course of Wolman disease is caused by genetic defects of LAL that leave no residual enzyme activity. In a CESD patient, a G-to-A transition at position -1 of the exon 8 splice donor site resulted in skipping of exon 8 in 97% of the mRNA originating from this allele, while 3% was spliced correctly, resulting in full-length LAL enzyme.
