Genes affected
SYK (HGNC:11491): (spleen associated tyrosine kinase) This gene encodes a member of the family of non-receptor type Tyr protein kinases. This protein is widely expressed in hematopoietic cells and is involved in coupling activated immunoreceptors to downstream signaling events that mediate diverse cellular responses, including proliferation, differentiation, and phagocytosis. It is thought to be a modulator of epithelial cell growth and a potential tumour suppressor in human breast carcinomas. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2010]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SYK. . Gene score misZ 2.9041 (greater than the threshold 3.09). Trascript score misZ 3.945 (greater than threshold 3.09). GenCC has associacion of gene with immunodeficiency 82 with systemic inflammation.
BP4
Computational evidence support a benign effect (MetaRNN=0.2308586).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2023The c.193A>G (p.T65A) alteration is located in exon 2 (coding exon 1) of the SYK gene. This alteration results from a A to G substitution at nucleotide position 193, causing the threonine (T) at amino acid position 65 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
