found unannotated gene via rna-seq, can i use public datasets (raw data) to find clinical info about this gene?

Question

[Taktak31]

if i found an unannotated gene in a cell line via rna-seq, can i use GEO or TCGA (download raw data) and find if this gene is up/downregulated in patient samples?

How would you match an "unannotated" gene to other datasets? Or do you mean entries such as LINC*/LOC* that are unspecified loci/long non coding RNAs (I'm going off of the tag you've used)

[Taktak31]

i am trying to use the chromosome location to ID it in raw data sets. is this possible?

[Ram]

What do you mean by "ID it" and "raw datasets"?
