Dear Trang,
Have you made sure that the variants you input are part of the 1000 genomes EAS reference panel?
When I check a very small subset of your inputted variants they do not seem to be present in the selected reference panel.
Variants which are not part of the reference panel are dropped from the analysis by FUMA.
If the variants you have inputted should be present in the reference panel, then please check whether your provided genomic coordinates are provided as mapped in hg19.
I hope this answers your question, please let me know if I can help you any further.
Cheers,
Marijn
