Trait
Abnormal T cell morphology
Abnormal increase or decrease of total or subset T cell count. T cells are commonly characterized as CD3+ lymphocytes, or their subpopulations, in the blood, compared to a reference range for a given sex and age-group, measured ex vivo. These may include both TCR alpha/beta and gamma/delta T cells.

Changes in these genes cause rare conditions in which Abnormal T cell morphology 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 |
|---|---|---|
| CD28CD28 molecule | Very often (80–99%) | In 1 condition |
| CTLA4cytotoxic T-lymphocyte associated protein 4 | Very often (80–99%) | In 1 condition |
| PNPpurine nucleoside phosphorylase | Very often (80–99%) | In 1 condition |
| TNFRSF1BTNF receptor superfamily member 1B | Very often (80–99%) | In 1 condition |
| CD4CD4 molecule | Not recorded | In 1 condition |
| SMARCAL1SNF2 related chromatin remodeling annealing helicase 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.
