LPIN2 and Majeed syndrome: Lipin 2 is hypothesized to exhibit anti-inflammatory functions through PAP activity with respect to its expression in erythrocytes and lymphoid cells, the loss of which is postulated to contribute to the chief manifestations of Majeed syndrome that cannot be compensated for by lipin 1 and lipin 3 due to the much higher levels of lipin 2 within these tissues [25].
