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=0.24408099).

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Mar 13, 2022 | 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with LYN-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 25 of the LYN protein (p.Arg25His). - |
