Genes affected

ITK (HGNC:6171): (IL2 inducible T cell kinase) This gene encodes an intracellular tyrosine kinase expressed in T-cells. The protein contains both SH2 and SH3 domains which are often found in intracellular kinases. It is thought to play a role in T-cell proliferation and differentiation. [provided by RefSeq, Jul 2008]

ITK Gene-Disease associations (from GenCC):

• lymphoproliferative syndrome

  Inheritance: AR Classification: DEFINITIVE Submitted by: G2P
• lymphoproliferative syndrome 1

  Inheritance: AR Classification: DEFINITIVE, STRONG, MODERATE Submitted by: ClinGen, Ambry Genetics, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
