Objective To establish the pathogenic gene loci on 8q23.3-24.1 and 10p15 in this benigh adult familial myoclonic epilepsy (BAFME) pedigree.Methods After obtaining informed consent, peripheral blood samples were obtained from 7 BAFME patients and 13 control individuals;amplified polymerase chain reaction (PCR) and short tandem repeat (STR) method were employed to conduct linkage analysis;five STRs on chromosomal segments 8q23.3-q24.1 and three STRs on chromosomal segments 10p1 5 were chosen at genetic distances appropriate.Results Negative signal was all obtained for 8q23.3-q24.1 and 10p15 (LOD scores less than-2 for these STRs, respectively;θ=0.0), excluding involvement of these regions in the BAFME pedigree analyzed.Conclusion STR linkage analysis of 8q23.3-q24.1 and 10p 15 does not support linkage to these regions, indicating that the pathogenic gene in the pedigree we studied is not in these chromosome segments.
