CD7 (Cluster of Differentiation 7) is a protein that in humans is encoded by the CD7 gene.^[5]

Function[edit]

This gene encodes a transmembrane protein which is a member of the immunoglobulin superfamily. This protein is found on thymocytes and mature T cells. It plays an essential role in T-cell interactions and also in T-cell/B-cell interaction during early lymphoid development.^[5]

See also[edit]

• Cluster of differentiation
• DC-7

Interactions[edit]

CD7 has been shown to interact with PIK3R1.^[6][7]

Clinical significance[edit]

CD7 can be aberrantly expressed in refractory anaemia with excess blasts (RAEB) and may confer a worse prognosis.^[8] Also, a lack of CD7 expression could insinuate mycosis fungoides (MF) or Sezary syndrome (SS).^[9]
