Genes affected
LCK (HGNC:6524): (LCK proto-oncogene, Src family tyrosine kinase) This gene is a member of the Src family of protein tyrosine kinases (PTKs). The encoded protein is a key signaling molecule in the selection and maturation of developing T-cells. It contains N-terminal sites for myristylation and palmitylation, a PTK domain, and SH2 and SH3 domains which are involved in mediating protein-protein interactions with phosphotyrosine-containing and proline-rich motifs, respectively. The protein localizes to the plasma membrane and pericentrosomal vesicles, and binds to cell surface receptors, including CD4 and CD8, and other signaling molecules. Multiple alternatively spliced variants encoding different isoforms have been described. [provided by RefSeq, Aug 2016]

Severe combined immunodeficiency due to LCK deficiency Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Dec 13, 2021 | This sequence change creates a premature translational stop signal (p.Arg39*) in the LCK gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in LCK are known to be pathogenic (PMID: 22985903, 27087313). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with LCK-related conditions. For these reasons, this variant has been classified as Pathogenic. - |
