hm1

• Allelic Composition: Disc1^del/Disc1^del
• Genetic Background: B6.129S6-Disc1^del

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

behavior/neurological

abnormal learning/memory/conditioning ( J:107244 )

• mice show consistent impairment in the working memory test

• however, mice learn and perform tasks similarly to wild-type and no brain abnormalities are noted

ht2

• Allelic Composition: Disc1^{tm1(DISC1/DISC1FP1,DISC1FP1/DISC1,DISC1)Xzho}/Disc1^del
• Genetic Background: 129S2/SvPasCrl-Disc1^del Disc1^{tm1(DISC1/DISC1FP1,DISC1FP1/DISC1,DISC1)Xzho}

growth/size/body

decreased body size ( J:214737 )

♂ • males, but nor females, are slightly, but significantly, smaller than control littermates

decreased body weight ( J:214737 )

♂ • males, but not females, show slightly, but significantly, reduced body weight at P103

behavior/neurological

abnormal behavioral response to xenobiotic ( J:214737 )

♂ • males show a larger increase in total distance traveled, counts, and transitions in locomotion after ketamine injection in all time blocks except for the first and last one than sibling controls, indicating increased and prolonged responses to ketamine

low sweet preference ( J:214737 )

♀ • females, but not males, show a lower preference for saccharin than control females

behavioral despair ( J:214737 )

• mice show more immobility time in the tail suspension test, indicating behavioral despair

increased startle reflex ( J:214737 )

• mice exhibit higher startle with less variation between individuals

hematopoietic system

anemia ( J:214737 )

♂ • incomplete penetrance, seen in 2 of 10 males

decreased hemoglobin content ( J:214737 )

♂ • 2 of 10 males show lower concentrations of hemoglobin, indicating different degrees of anemia

increased red blood cell distribution width ( J:214737 )

• increase in red blood cell distribution width

nervous system

nervous system phenotype ( J:214737 )

N • no gross anatomical abnormalities are seen in the brain

increased prepulse inhibition ( J:214737 )

• mice exhibit enhanced prepulse inhibition (PPI), or impaired prepulse facilitation, when PPI is conducted with a short ISI at 25 ms
