Hermansky-Pudlak Syndrome (HPS), a recessively inherited disease in humans, affects the biosynthesis/processing of the related intracellular organelles: lysosomes, melanosomes, and platelet dense granules. The disease is multigenic in both humans and mice where 14 separate genes have been demonstrated to be causative. Patients often die prematurely with severe lung abnormalities. Patients with the related Chediak-Higashi Syndrome (CHS) likewise have significantly reduced life spans. Long-term survival and lung histomorphology were analyzed in a pilot experiment involving several genetically defined singly and doubly mutant mouse HPS mutants and the beige CHS mutant to determine whether these parameters are altered in the mouse models. The mutants differed widely in both longevity and lung architecture. Mice doubly homozygous for the pale ear and ruby eye or for the muted and pearl genes had the shortest life spans with none surviving the two-year experimental duration. Life spans were similarly severely reduced in the beige and gunmetal mutants. Intermediate life spans were apparent in the pearl, pallid, and cocoa mutants whereas minimal effects were noted in ruby eye, muted, light ear, and cocoa mutants. Enlarged air spaces were noted in histologic sections of lungs of several of the mutants. For the most part, the severity of lung abnormalities was inversely proportional to the long-term survival of these various mutants, suggesting that lung pathology may contribute to mortality, as has been suggested for human HPS patients.
