Among mice of strain SB/Le, homozygous for the mutant beige (bg), satin (sa) and white-bellied agouti (Aw), 70% developed progressive pneumonitis by 6 mth of age. Among backcross offspring from an outcross to C57BL/6J-Aw-J, 49% of homozygous beige and 11% of non-beige genotypes developed pneumonitis by 6 mth of age. The evidence indicates that a specific action of the beige gene increases susceptibility to progressive pneumonitis. Beige mice show giant lysosomal granules in the leucocytes and pigment dilution closely analogous to the Chediak-Higashi syndrome in man and similar disorders in mink and cattle.
