      • 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.

    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 19.6 kb of the gene's 97 kb; 738 of those bases code for the protein.

    How a genome test reads FGF13

    3

    positions in FGF13 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 97 kb of FGF13, introns included, not only the 19.6 kb of exons.
