RESUMEN

Objective@#To analyze the CYP2C19 gene polymorphism in patients with upper digestive system diseases in Anhui Province, so as to provide evidence for individual treatment.@*Methods@#The 307 patients with upper digestive system diseases in the Department of Gastroenterology, The 901st Hospital of Combined Service Force of People's Liberation Army were selected. The CYP2C19 genotypes were detected by DNA microarray microarray. The CYP2C19 genotypes and metabolic types in different genders, ages and diseases were analyzed.@*Results@# There were 197 males ( 64.17% ) and 110 females ( 35.83% ) , with the age of ( 58.00±16.13 ) years old. The gene frequency of CYP2C19*1, CYP2C19*2 and CYP2C19*3 was 62.70%, 32.25% and 5.05%, respectively. There were 119 cases (38.76%) of *1/*1 ( 636GG, 681GG ), 129 cases ( 42.02% ) of *1/*2 ( 636GG, 681GA ) , 18 cases (5.86%) of *1/*3 ( 636GA, 681GG ) , 29 cases ( 9.45% ) of *2/*2 ( 636GG, 681AA ) , 11 cases ( 3.58% ) of *2/*3 ( 636GA, 681GA ) , and 1 cases ( 0.33% ) of *3/*3 ( 636AA, 681GG ). In terms of metabolisms, there were 119 cases ( 38.76% ) of fast metabolism type, 147 cases (47.88%) of intermediate metabolism type and 41 cases (13.35%) of slow metabolism type. There were no significant differences in CYP2C19 genotypes and metabolic types among the patients with different gender, age and digestive system diseases ( P>0.05 ).@*Conclusion@#The CYP2C19 genotypes of patients with upper digestive system diseases were polymorphic, mainly the fast metabolism type and the intermediate metabolism type, which could provide reference for the clinical medication of individualized treatment of proton pump inhibitors.

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>
