I have queried using Entrez Utilities (efetch: https://www.ncbi.nlm.nih.gov/books/NBK25499/) and obtained annotations for transcripts like the following:
1 2557 gene
gene SAMD11 gene_syn MRS gene_desc sterile alpha motif domain containing 11 db_xref GeneID:148398 db_xref HGNC:HGNC:28706 db_xref MIM:616765
How/what database should I query to get the proper genomic coordinates for this gene and convert the transcript coordinates to absolute genomic coordinates?
IMPORTANT!: many of these transcripts are out of date, so just getting a table from UCSC is out of the question (unless transcript ID doesn't matter for getting genomic coordinates...)
