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.

SKAP1-AS1 (HGNC:53166): (SKAP1 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.377C>T (p.S126L) alteration is located in exon 6 (coding exon 6) of the SKAP1 gene. This alteration results from a C to T substitution at nucleotide position 377, causing the serine (S) at amino acid position 126 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
