This cluster includes 3 inhibitory lectin receptors expressed on myeloid and/or NK cells (CLEC1A [63], KLRA1 [64], KLRA3 [65]), KLRA10, which is closely related in structure to inhibitory Ly49C receptors [66], and MGL2, a marker for pro-tumor macrophages [67]. The gene discussed is KLRA1P; the disease is neoplasm.
