== Pathology ==

Much of the current knowledge about Lyn has emerged from studies of genetically manipulated mice. Lyn deficient mice display a phenotype that includes splenomegaly, a dramatic increase in numbers of myeloid progenitors and monocyte/macrophage tumors.  Biochemical analysis of cells from these mutants revealed that Lyn is essential in establishing ITIM-dependent inhibitory signaling and for activation of specific protein tyrosine phosphatases within myeloid cells.<ref name="Harder2001" />

Mice that expressed a hyperactive Lyn allele were tumor free and displayed no propensity toward hematological malignancy.  These mice have reduced numbers of conventional B lymphocytes, down-regulated surface immunoglobulin M and costimulatory molecules, and elevated numbers of B1a B cells.  With age these animals developed a glomerulonephritis phenotype associated with a 30% reduction in life expectancy.<ref name="pmid12486102">{{cite journal | vauthors = Hibbs ML, Harder KW, Armes J, Kountouri N, Quilici C, Casagranda F, Dunn AR, Tarlinton DM | title = Sustained activation of Lyn tyrosine kinase in vivo leads to autoimmunity | journal = The Journal of Experimental Medicine | volume = 196 | issue = 12 | pages = 1593–604 | date = Dec 2002 | pmid = 12486102 | pmc = 2196073 | doi = 10.1084/jem.20020515 | url = http://www.jem.org/cgi/pmidlookup?view=long&pmid=12486102 }}</ref>
