Objective:
To investigate the gene mutation of lipoprotein lipase(LPL) of familial LPL deficiency in China.
Methods:
The DNA sequencing of LPL gene of the patients was performed with the dideoxy method based on the polymerase chain reaction amplification using the genomic DNA as a template.
Results:
It was identified that a missense mutation in exon 6 of LPL gene (6G(979)-->A) resulted in the substitution of Glu(242) by Lys in a heterozygous state.
Conclusion:
The missense mutation of LPL may play a key role in the decrease of LPL activity. This is the first report about the gene mutation of LPL at this site in familial LPL deficiency. Moreover, it contributes to the elucidation of the pathophysiological mechanisms of atherosclerosis and some metabolic diseases.
