Mouse lines carrying:
frg mutation (1 available); any frg mutation (1 available)
phenotype observed in females
phenotype observed in males
N normal phenotype

frg/frg mice (left) exhibit a small body size and a shortened face with wide set eyes

craniofacial
• the shortened face phenotype has varied penetrance

growth/size/body
• the shortened face phenotype has varied penetrance

reproductive system
• breeding a male or female homozygote with a heterozygote yields a litter size of 3 to 4 pups while heterozygote x heterozygote matings yield average litter sizes of 6 to 7

vision/eye
• wide set eyes is a consistent phenotype in homozygotes

skeleton
• skull bone mineral density is greater in female homozygotes than controls and less in male homozygotes than controls
