Nullizygous mutations cause tremors, ataxia, altered lipid homeostasis, increased foam cell number, Purkinje cell loss and premature death, and may lead to hepatosplenomegaly, hunched posture, reduced weight, abnormal apoptosis, sperm defects, dyspnea, and high susceptibility to bacterial infection.
