LAX1

protein-coding

lymphocyte transmembrane adaptor 1

Gene summary

Enables SH2 domain binding activity and protein kinase binding activity. Involved in several processes, including B cell activation; negative regulation of MAPK cascade; and negative regulation of T cell activation. Located in Golgi apparatus; cytosol; and plasma membrane. [provided by Alliance of Genome Resources, Jul 2025]

ClinVar Variants & Pathogenicity by Type

Statistics based on transcript NM_017773.4. Only rare variants are included.

We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.

Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.
