How GTPBP2 is laid out
- Coding sequence
- Untranslated region
- Intron
- Direction of transcription
- Known disease-causing sites
- Stretches short reads find hard
Exons of the gene's MANE Select transcript (release v1.5), from NCBI and EMBL-EBI, on the GRCh38 reference genome.
Chromosome bands from UCSC's GRCh38 ideogram (2022-10-29).
Nearby genes from Ensembl release 116, on GRCh38.
Exons make up 3 kb of the gene's 8.8 kb; 1,809 of those bases code for the protein.
How a genome test reads GTPBP2
6
positions in GTPBP2 where ClinVar classes a change as pathogenic or likely pathogenic
None of them falls in a region short reads find hard.
A whole genome covers all 8.8 kb of GTPBP2, introns included, not only the 3 kb of exons.
