N normal phenotype
mortality/aging
• normal numbers of pups are born but most die within 24 hours

craniofacial
• enlarged front fontanelle is present in mutants
• calvarium of adult homozygotes has wider frontal bones than wild-type littermates resulting in a wider distance between the eyes
• nasal bone of adults is shorter than in wild-type

growth/size/body
• at birth, mutants are less than 2/3 the weight of normal littermates

hematopoietic system
• at P1, many thymocytes are dead or dying
• thymuses of P1 mutants are much smaller than those of controls

immune system
• at P1, many thymocytes are dead or dying
• thymuses of P1 mutants are much smaller than those of controls

skeleton
• enlarged front fontanelle is present in mutants
• calvarium of adult homozygotes has wider frontal bones than wild-type littermates resulting in a wider distance between the eyes

vision/eye
• mutants display a wider distance between the eyes

cellular
• at P1, many thymocytes are dead or dying

endocrine/exocrine glands
• at P1, many thymocytes are dead or dying
