🧪 Basic GraphQL API for a Bioinformatics Case

Data Schema

Are you looking for an daily life analogy instead of gene, transcript, expression_profiles terms?

You could think of an author instead of a gene. So, our authors (genes) might have more than one book (transcript). Also, each book (transcript) could have more than one version/type and - so, their meta information also change!

Example Queries

Here, I provided some queries to demonstrate the use of GraphQL API. Feel free to play around with them to learn more!

Example Gene IDs: GeneID1, GeneID2 Example Gene Names: GeneName1, GeneName2 Example Transcript IDs: TranscriptID1.1, TranscriptID1.2, TranscriptID1.3, TranscriptID2.1, TranscriptID2.2

Query all the genes and transcript IDs of each gene

query {
  genes {
    gene_id
    gene_name
    gene_description
    transcripts {
      transcript_id
    }
  }
}

Query all transcripts

query {
  transcripts {
    transcript_id
    length
  }
}

Query all the transcripts for the gene with the gene_id of "GeneID2"

query {
  transcripts(gene_id: "GeneID2") {
    gene_id
    transcript_id
    length
  }
}

Query the all transcripts, their lengths and expression profiles for "GeneName1":

query {
  genes(gene_name: "GeneName1") {
    gene_id
    gene_name
    gene_description
    transcripts {
      transcript_id
      length
      expression_profiles {
        brain
        heart
      }
    }
  }
}

Query the expression profile for the transcript with the transcript_id of "TranscriptID2.1"

query {
  expression_profiles(transcript_id: "TranscriptID2.1"){
    transcript_id
    brain
    heart
  }
}
