Abstract:
:In this study, through linkage analysis of a four-generation Chinese family with multiple members afflicted with DGI (type II), we identified a novel missense mutation in DSPP. The mutation was located in exon 2 at the second nucleotide position of the last codon and resulted in a substitution of a proline with a leucine residue (c.50C>T, p.P17L, g.50C>T). To assess the potential effects of this novel mutation, we utilized various bioinformatics analysis programs. The results indicate that the mutation likely affects protein cleavage/trafficking. We also analyzed previously reported mutations of DSPP. In summary, our finding supports that the genomic sequence that corresponds to the P17 residue of DSPP is a mutational hotspot and P17 may be critical for the function of DSPP.
