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 GeneticsOct 06, 2021The c.28A>T (p.I10F) alteration is located in exon 1 (coding exon 1) of the SKAP1 gene. This alteration results from a A to T substitution at nucleotide position 28, causing the isoleucine (I) at amino acid position 10 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
