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 8.1 kb of the gene's 21 kb; 7,311 of those bases code for the protein.

How a genome test reads ABCA2

12

positions in ABCA2 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 21 kb of ABCA2, introns included, not only the 8.1 kb of exons.

Traits linked to ABCA2

The Human Phenotype Ontology lists these as features of the rare conditions ABCA2 can cause. Each trait's page lists the other genes linked to it.
