Genes affected

CD53 (HGNC:1686): (CD53 molecule) The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This encoded protein is a cell surface glycoprotein that is known to complex with integrins. It contributes to the transduction of CD2-generated signals in T cells and natural killer cells and has been suggested to play a role in growth regulation. Familial deficiency of this gene has been linked to an immunodeficiency associated with recurrent infectious diseases caused by bacteria, fungi and viruses. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]

LRIF1 (HGNC:30299): (ligand dependent nuclear receptor interacting factor 1) Predicted to enable retinoic acid receptor binding activity. Involved in dosage compensation by inactivation of X chromosome. Located in Barr body; centriolar satellite; and nucleoplasm. Colocalizes with chromosome, telomeric region.
