    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 10.3 kb of the gene's 433.4 kb; 7,119 of those bases code for the protein.

    How a genome test reads ARID1B

    274

    positions in ARID1B 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 433.4 kb of ARID1B, introns included, not only the 10.3 kb of exons.
