RESUMEN

<p><b>OBJECTIVE</b>To detect the MSX1 gene mutation in a Chinese family with oligodontia.</p><p><b>METHODS</b>Blood samples were obtained from seven affected and seven unaffected individuals in the pedigree. All exons and flanking intronic boundaries of the MSX1 gene were amplified with polymerase chain reaction technique and then directly sequenced. The website of bioinformatics was used to predict the effect of the mutation on the function.</p><p><b>RESULTS</b>A splicing mutation (IVS1-2A > G) was found at position -2 near the 3' end of the IVS1 of MSX1, which made a change of the intron 1 splice acceptor site. None of the mutation was found in normal individuals of the family and in 100 unrelated healthy matched control individuals.</p><p><b>CONCLUSIONS</b>IVS1-2A > G was a novel splicing mutation identified in the MSX-1 gene and it might be responsible for nonsyndromic oligodontia in this family.</p>

RESUMEN

<p><b>OBJECTIVE</b>To study a Chinese pedigree with Hailey-Hailey disease (HHD) and examine the ATP2C1 gene mutation in this family.</p><p><b>METHOD</b>All exons of ATP2C1 gene were analyzed with polymerase chain reaction and DNA sequencing in all patients of this family and 100 unrelated population-match controls.</p><p><b>RESULTS</b>We identified a novel heterozygous nucleotide A --> G transition at position 235 - 2 in intron 3 of ATP2C1 gene. This splice site mutation was not found in the healthy members of this pedigree and in the controls.</p><p><b>CONCLUSION</b>The splicing mutation can affect the result of transcription and translation, and it is a specific novel mutation of ATP2C1 gene.</p>
