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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2023The c.965G>A (p.R322H) alteration is located in exon 11 (coding exon 11) of the SKAP1 gene. This alteration results from a G to A substitution at nucleotide position 965, causing the arginine (R) at amino acid position 322 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
