Genes affected

GARIN3 (HGNC:28397): (golgi associated RAB2 interactor family member 3) Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

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]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.20200646).

The c.1807A>G (p.K603E) alteration is located in exon 2 (coding exon 2) of the FAM71B gene. This alteration results from a A to G substitution at nucleotide position 1807, causing the lysine (K) at amino acid position 603 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
