The fasta annotation shows as above. I used to think that the fasta sequence will have one base removed when compared with the chromosome. But then I find the fasta sequence is exactly same as the chromosome and nothing removed. Now I don't know what does it mean. Hope you can help me. Thanks~

I think "one base removed" refers to when the gene is translated into protein, not the nucleotide sequence itself. You can see the sequence of this gene in NCBI sequence viewer, here.
Note the "A" highlighted in green in the second line, that is the "base removed to allow translational frameshift".
Now I see. The removed base is the 222635. But, can this gene be translated successfully? I mean, the base 222635 has caused a frameshift mutation and this fasta just wants to note there was a gene here. Or, this base will be removed by the organism during transcription or translation.
