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

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), LYN. . Gene score misZ 3.3381 (greater than the threshold 3.09). Trascript score misZ 3.9896 (greater than threshold 3.09). GenCC has associacion of gene with autoinflammatory disease, systemic, with vasculitis.
BP4
Computational evidence support a benign effect (MetaRNN=0.1290519).

Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 14, 2023This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 41 of the LYN protein (p.Gln41Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with LYN-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
