How PGA3 is laid out
- Coding sequence
- Untranslated region
- Intron
- Direction of transcription
- 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 1.6 kb of the gene's 9.6 kb; 1,167 of those bases code for the protein.
Sequencing PGA3
65High
How hard PGA3 is to sequence with short reads, out of 100Each bar is the share of PGA3's exon bases in that kind of difficult region. The score weighs them by how much each costs a short-read call: 0 when no base is in any, 100 when every base is in all of them.
- MappabilityStretches where 100 or 250 bp reads cannot be placed uniquely, so a call there may be missing or wrong. Weight 35%.100%
- HomologySegmental duplications: copies elsewhere in the genome, such as paralogues and pseudogenes, at 90% identity or more. Weight 30%.100%
- RepeatsTandem repeats and runs of one base, which reads slip on and may not span. Weight 15%.0%
- GC contentWindows under 25% or over 65% G and C, which library preparation covers thinly. Weight 10%.2.6%
- Reference coverageGaps in the reference assembly nearby, where there is no sequence for reads to align to. Weight 10%.0%
