Genes affected

LOC107985145 (HGNC:):

EPB41L3 (HGNC:3380): (erythrocyte membrane protein band 4.1 like 3) Predicted to enable cytoskeletal protein-membrane anchor activity. Predicted to be a structural constituent of cytoskeleton. Predicted to be involved in several processes, including nervous system development; paranodal junction maintenance; and protein localization to paranode region of axon. Located in cell-cell junction and plasma membrane. Biomarker of meningioma. [provided by Alliance of Genome Resources, Apr 2022]
