Nirvana JSON File Format

Overview

Conventions

In the Nirvana JSON representation, we try to maximize the amount of useful information that is relayed in the output file. As such, we have several conventions that are useful to know about:

  • With boolean key/value pairs, we only output the keys that have a true value. I.e. there's no reason to display "isStructuralVariant":false a few million times when annotating a small variant VCF.
  • When transferring data from the VCF file to the JSON (e.g. for allele depths (AD)), it is common to use a period (.) as a placeholder for missing data in the VCF file. Nirvana treats periods like empty or null strings and therefore will not output those entries.

JSON Layout

info

In general, each position corresponds to a row in the original VCF file.

For each gene that was referenced in the transcripts found in the positions section, there will be additional gene-level annotation in the gene section.

Parsing

info

We've put together a new section that discusses how to parse our JSON files easily using examples in a Python Jupyter notebook and a R version as well. In addition, we have information about how to quickly dump content from our JSON file using a tabix-like utility called JASIX.

If a sample does not contain any entries, we will create a sample object that contains the isEmpty key. This ensures that sample ordering is preserved while indicating that a sample is intentionally empty.

Reference Minor Alleles

Nirvana supports annotating reference minor alleles. In such a case, refAllele will be replaced by the global major allele and altAllele will be replaced with the original reference allele.

Flagging Decomposed & Recomposed Variants

When two or more decomposed variants are recomposed into an MNV, the decomposed variants will be marked with "isDecomposedVariant":true.

Similarly, the recomposed variant will be shown as a new VCF position. This recomposed variant will be flagged with "isRecomposedVariant":true.

Genes

"summary":"This gene encodes a member of the DNA mismatch repair MutS family. In E. coli, the MutS protein helps in the recognition of mismatched nucleotides prior to their repair. A highly conserved region of approximately 150 aa, called the Walker-A adenine nucleotide binding motif, exists in MutS homologs. The encoded protein heterodimerizes with MSH2 to form a mismatch recognition complex that functions as a bidirectional molecular switch that exchanges ADP and ATP as DNA mismatches are bound and dissociated. Mutations in this gene may be associated with hereditary nonpolyposis colon cancer, colorectal cancer, and endometrial cancer. Transcripts variants encoding different isoforms have been described.

"description":"The transcription factor p53 responds to diverse cellular stresses to regulate target genes that induce cell cycle arrest, apoptosis, senescence, DNA repair, or changes in metabolism. In addition, p53 appears to induce apoptosis through nontranscriptional cytoplasmic processes. In unstressed cells, p53 is kept inactive essentially through the actions of the ubiquitin ligase MDM2, which inhibits p53 transcriptional activity and ubiquitinates p53 to promote its degradation. Numerous posttranslational modifications modulate p53 activity, most notably phosphorylation and acetylation. Several less abundant p53 isoforms also modulate p53 activity. Activity of p53 is ubiquitously lost in human cancer either by mutation of the p53 gene itself or by loss of cell signaling upstream or downstream of p53 (Toledo and Wahl, 2006; Bourdon, 2007; Vousden and Lane, 2007)",

Mapping

  1. disorder was positioned by mapping of the wild type gene
  2. disease phenotype itself was mapped
  3. molecular basis of the disorder is known
  4. disorder is a chromosome deletion or duplication syndrome

Inheritance

  • autosomal recessive
  • autosomal dominant

Comments

  • contributes to the susceptibility to multifactorial disorders
  • variations that lead to apparently abnormal laboratory test values
  • unconfirmed mapping
