I have downloaded a gene expression data from GEO database (GSE3268) in which in some of its rows there are duplicate gene symbols.
For example TP53 exists in two rows with different expression values and different GenBank Accession IDs.
They have the following Nucleotide Title:
Human p53 cellular tumor antigen mRNA, complete cds
Homo sapiens tumor protein p53 (TP53), transcript variant 1, mRNA
I want to map these data with edge list of gene symbols to make a network. Which expression value should I consider for such duplicate gene symbols for mapping?
