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 6 kb of the gene's 28.8 kb; 5,823 of those bases code for the protein.

How a genome test reads MYH3

38

positions in MYH3 where ClinVar classes a change as pathogenic or likely pathogenic

1 of them (2.6%) falls in a region short reads find hard.

  • Low mappability (1 site)Regions where 100 bp or 250 bp reads cannot be placed uniquely.

A whole genome covers all 28.8 kb of MYH3, introns included, not only the 6 kb of exons.

Where this comes from

  • HGNC: the gene's symbol, name, other symbols and location.
  • MANE Select v1.5, from NCBI and EMBL-EBI: the transcript, its exons and coding sequence.
  • ClinVar and the GIAB stratifications: known disease-causing sites, and the regions short reads find hard.
  • The Human Phenotype Ontology, release 2026-09-01: the traits linked to the gene. Find out more at hpo.jax.org.
  • Data release 2026.10.16-c6eea6bf.
