hm1

• Allelic Composition: frg/frg
• Genetic Background: A/J-frg/GrsrJ

• ♀: 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

decreased cranium height ( J:128473 )

short maxilla ( J:128473 )

short face ( J:128473 )

• the shortened face phenotype has varied penetrance

short snout ( J:128473 )

growth/size/body

short maxilla ( J:128473 )

short face ( J:128473 )

• the shortened face phenotype has varied penetrance

short snout ( J:128473 )

decreased body size ( J:128473 )

reproductive system

decreased litter size ( J:128473 )

• 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

ocular hypertelorism ( J:128473 )

• wide set eyes is a consistent phenotype in homozygotes

skeleton

decreased cranium height ( J:128473 )

short maxilla ( J:128473 )

abnormal bone mineral density ( J:128473 )

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