Genes affected

LYN (HGNC:6735): (LYN proto-oncogene, Src family tyrosine kinase) This gene encodes a tyrosine protein kinase, which maybe involved in the regulation of mast cell degranulation, and erythroid differentiation. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2011]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.27).
• BP6: Variant 8-55942004-T-A is Benign according to our data. Variant chr8-55942004-T-A is described in ClinVar as [Likely_benign]. Clinvar id is 2964008.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS2: High AC in GnomAdExome at 5 AD gene.
