The NM_003177.7(SYK):c.1836-49A>T variant causes a intron change involving the alteration of a non-conserved nucleotide. The gene SYK is a tumor suppressor gene (CancerMine: 39 TSG, 35 oncogene, 13 driver citations). The gene SYK is a known oncogene (CancerMine: 39 TSG, 35 oncogene, 13 driver citations). The gene SYK is a cancer driver gene (CancerMine: 39 TSG, 35 oncogene, 13 driver citations). The variant allele was found at a cumulative frequency of 0.557 (AC=892,966) in the gnomAD database across 1,602,760 control chromosomes, including 251,630 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.719. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★).

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]
