MGI Phenotype

FUNCTION: This gene encodes a component of high density lipoproteins (HDL). Mice lacking the encoded protein have low HDL-cholesterol levels, smaller HDL particles, increased clearance of triglyceride-rich lipoproteins and insulin hypersensitivity. Transgenic mice overexpressing the encoded protein have elevated levels of HDL-cholesterol and show increased susceptibility to atherosclerosis. Alternative splicing of this gene results in multiple variants. [provided by RefSeq, Mar 2015]
PHENOTYPE: Homozygous null mutation of this gene results in a reduction of total cholesterol, HDL cholesterol, free fatty acids, insulin, and glucose levels in both the fasted and unfasted states. Strain specific alleles have been associated with varying degrees of amyloidosis. [provided by MGI curators]
