Epilepsy (Full Panel)
- Epilepsy
One of 171 genes linked to it
A brain disorder characterized by episodes of abnormally increased neuronal discharge resulting in transient episodes of sensory or motor neurological dysfunction, or psychic dysfunction. These episodes may or may not be associated with loss of consciousness or convulsions.
- 2 GenCC submitters rate it definitive or strong
How EEF1A2 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 1.8 kb of the gene's 11.1 kb; 1,392 of those bases code for the protein.
How a genome test reads EEF1A2
27
positions in EEF1A2 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 11.1 kb of EEF1A2, introns included, not only the 1.8 kb of exons.
