## TL;DR

TCL1A (T-cell leukaemia/lymphoma protein 1A) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as a tumour suppressor and a fusion partner, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Non-Hodgkin lymphoma, Skin cancer, Diffuse large B-cell lymphoma and 1 more.

## Summary

Enhances the phosphorylation and activation of AKT1, AKT2 and AKT3. Promotes nuclear translocation of AKT1. Enhances cell proliferation, stabilises mitochondrial membrane potential and promotes cell survival.

Open Targets scores its association with cancer at 0.62 (direct and indirect evidence; datatypes literature 0.76, genetic association 0.48, somatic mutation 0.89). IntOGen calls it a driver in 1 cohort (0 activating, 1 loss-of-function), covering Diffuse Large B-Cell Lymphoma, NOS.

- Where found: Non-Hodgkin lymphoma: Open Targets association 0.56 with non-Hodgkin lymphoma (MONDO_0018908); Skin cancer: Open Targets association 0.51 with skin cancer (MONDO_0002898); Diffuse large B-cell lymphoma: IntOGen driver in 1 cohort (DLBCLNOS); Melanoma: Open Targets association 0.51 with melanoma (MONDO_0005105)

## Notes

- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: IntOGen calls it a loss-of-function (LoF) driver in 1 cohort; UniProt disease notes describe a translocation or gene fusion involving the gene. Evidence tier "cohort-driver" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
