phenotype observed in females
phenotype observed in males
N normal phenotype
behavior/neurological

pigmentation
• darker than the commonly known pigmentation umbrous (J:163587)

digestive/alimentary system

immune system
N
• activated T cells exhibit normal IL2 production
• large and often multinucleated
• cytoplasm appears laminated, infrequently containing large crystals
• erythroid progenitor cells predominate
• includes hyperplasia of follicles and distention of medullary sinusoids with plasma cells
• of the skin, especially the ears
• presumably due to scratching

integument
• darker than the commonly known pigmentation umbrous (J:163587)
• especially the ears

hematopoietic system
• large and often multinucleated
• cytoplasm appears laminated, infrequently containing large crystals
• erythroid progenitor cells predominate

homeostasis/metabolism
• associated with pulmonary chronic interstitial inflammation and alveolar proteinosis

mortality/aging
• severe immune disease results in death between 4 and 6 months of age attributed to hypoxia

respiratory system
• large and often multinucleated
• cytoplasm appears laminated, infrequently containing large crystals
• a variable minimal infiltrate of neutrophils is seen
• many line alveoli and are large containing clear cytoplasmic vacuoles
