Gene Expression + Phenotype

Homozygotes for a null allele show altered taste responses to fatty acids. Homozygotes for another null allele develop obesity, liver steatosis, and impaired glucose metabolism, adipogenesis and lipogenesis on a high-fat diet. Homozygotes for a third allele show altered islet somatostatin secretion.
