: Some tumors have evolved to "shed" MICA from their surface. By releasing these proteins into the bloodstream, the cancer cells can "blind" the immune system’s NK cells, allowing the tumor to grow undetected [3, 8].
is a specific genetic variant identifier associated with the MICA (MHC class I polypeptide-related sequence A) gene . This nomenclature is primarily used in specialized genomic databases to catalog variations in the MICA protein, which plays a critical role in the human immune system's ability to detect stressed or infected cells. Core Function of the MICA Gene
The MICA gene encodes a cell surface glycoprotein that acts as a "distress signal." Dnaddr.Mica_P-1-10.1.var
: Specific MICA alleles and variants are linked to increased susceptibility to conditions like Celiac disease , Psoriasis , and Type 1 Diabetes [2, 7].
: Under normal conditions, MICA is rarely expressed on healthy cells. However, it becomes highly expressed when cells undergo viral infection, malignant transformation (cancer), or heat shock [2, 3]. : Some tumors have evolved to "shed" MICA from their surface
: These segments typically denote the specific position of the variation within the protein sequence or a versioned entry in a genomic assembly [4, 5]. Clinical and Biological Significance
: MICA antibodies are a known factor in the rejection of kidney and heart transplants. Discrepancies between the donor's and recipient's MICA variants can trigger an immune response [6]. This nomenclature is primarily used in specialized genomic
: Often refers to a specific database or data-processing pipeline used for variant annotation. Mica_P : Indicates the protein product (P) of the MICA gene.
