Trait
Z-band streaming
Streaming or smearing of the Z band, which is then no longer confined to a narrow zone which bisects the I band. The Z disk may extend across the I band or the entire sarcomere in a zigzag manner. Focal thickening, smudging, and blurring of the Z band takes place concurrently. Myofibrillar disorganization is a frequent but not invariable accompanying change.
Summary

Changes in these genes cause rare conditions in which Z-band streaming is seen. Most people with this trait have none of those conditions, and a gene on this list says nothing about anyone's own genome.
| Gene | How often it is seen | Conditions |
|---|---|---|
| CFL2cofilin 2 | Always | In 1 condition |
| HSPB8heat shock protein family B (small) member 8 | Always | In 1 condition |
| KYkyphoscoliosis peptidase | Always | In 1 condition |
| TNNT1troponin T1, slow skeletal type | Always | In 1 condition |
| TUBA4Atubulin alpha 4a | Always | In 1 condition |
| UNC45Bunc-45 myosin chaperone B | Always | In 1 condition |
| DESdesmin | Often (30–79%) | In 1 condition |
| ACTN2actinin alpha 2 | Not recorded | In 1 condition |
| FXR1FMR1 autosomal homolog 1 | Not recorded | In 1 condition |
| SQSTM1sequestosome 1 | Not recorded | In 1 condition |
How often is among people with one of the gene's conditions, the most often across them, as the Human Phenotype Ontology records it. These pages describe traits and the research behind them; they are not a diagnosis, and a doctor or genetic counsellor is the person to ask about symptoms.
