Dystonia, Myotonia, Paroxysmal Dyskinesia
- Paroxysmal DyskinesiaAutosomal dominant
Paroxysmal dyskinesia (PD) is a rare heterogenous group of movement disorders manifesting as abnormal involuntary movements that recur episodically and last only a brief time. PD includes paroxysmal kinesigenic dyskinesia (PKD), paroxysmal non-kinesigenic dyskinesia (PNKD), paroxysmal exertion-induced dyskinesia (PED) and a variant form of PKD, infantile convulsion and choreoathetosis (ICCA syndrome).
- 1 GenCC submitter rates it definitive or strong
- Inherited Dystonia
Umbrella term covering inherited dystonias, including DYT-TOR1A early-onset generalized dystonia, DYT-THAP1, myoclonus-dystonia (SGCE) and KMT2B-related dystonia.
- 2 GenCC submitters rate it definitive or strong
Broader groupings
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.
- ClinGen rates the link definitive
- 5 GenCC submitters rate it definitive or strong
Inheritance
- Autosomal dominant
- One changed copy, from either parent, is enough. A parent who has one passes it on to each child with a one-in-two chance.

- 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 3.4 kb of the gene's 33.5 kb; 1,479 of those bases code for the protein.
How a genome test reads SLC2A1

positions in SLC2A1 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 33.5 kb of SLC2A1, introns included, not only the 3.4 kb of exons.
