- 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 12.9 kb of the gene's 69.5 kb; 2,667 of those bases code for the protein.
How a genome test reads PTCHD1
8
positions in PTCHD1 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 69.5 kb of PTCHD1, introns included, not only the 12.9 kb of exons.
