Genes affected

SKAP1 (HGNC:15605): (src kinase associated phosphoprotein 1) This gene encodes a T cell adaptor protein, a class of intracellular molecules with modular domains capable of recruiting additional proteins but that exhibit no intrinsic enzymatic activity. The encoded protein contains a unique N-terminal region followed by a PH domain and C-terminal SH3 domain. Along with the adhesion and degranulation-promoting adaptor protein, the encoded protein plays a critical role in inside-out signaling by coupling T-cell antigen receptor stimulation to the activation of integrins.

The c.958C>T (p.L320F) alteration is located in exon 11 (coding exon 11) of the SKAP1 gene. This alteration results from a C to T substitution at nucleotide position 958, causing the leucine (L) at amino acid position 320 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
