• Allelic Composition: Sgcd^tm1Ojml/Sgcd⁺
• Genetic Background: B6.129-Sgcd^tm1Ojml

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

cardiovascular system

increased heart weight ( J:234761 )

♂ • 10 month old mice exercised for 22 weeks using a voluntary wheel running system show increased heart to body weight ratio

dilated cardiomyopathy ( J:234761 )

♂ • 1 year old mice develop a mild dilated cardiomyopathy phenotype after voluntary wheel running

♂ • however, under baseline conditions, 1 year old hearts do not show histological signs of dilated cardiomyopathy such as cell degeneration, necrosis and fibrosis and echocardiography shows no differences in fractional shortening and preserved left ventricular function

behavior/neurological

decreased aerobic running capacity ( J:234761 )

♂ • 10 month old mice exercised for 22 weeks using a voluntary wheel running system show reduced cumulative running distance over a period of 4 weeks from the age of 52 weeks

homeostasis/metabolism

decreased aerobic running capacity ( J:234761 )

♂ • 10 month old mice exercised for 22 weeks using a voluntary wheel running system show reduced cumulative running distance over a period of 4 weeks from the age of 52 weeks

abnormal response to exercise ( J:234761 )

♂ • 10 month old mice exercised for 22 weeks using a voluntary wheel running system show reduced cumulative running distance and increased heart to body weight ratio indicating mild cardiomyopathy

muscle

dilated cardiomyopathy ( J:234761 )

♂ • 1 year old mice develop a mild dilated cardiomyopathy phenotype after voluntary wheel running

♂ • however, under baseline conditions, 1 year old hearts do not show histological signs of dilated cardiomyopathy such as cell degeneration, necrosis and fibrosis and echocardiography shows no differences in fractional shortening and preserved left ventricular function

growth/size/body

increased heart weight ( J:234761 )

♂ • 10 month old mice exercised for 22 weeks using a voluntary wheel running system show increased heart to body weight ratio
