• Allelic Composition: Ighmbp2^nmd-2J/Ighmbp2^nmd-2J; Tg(Eno2-Ighmbp2)17Cx/?; Tg(Ttn-Ighmbp2)108Cx/?
• Genetic Background: involves: C57BL/6J * C57BLKS/J

cardiovascular system

increased heart weight ( J:102748 )

• increased heart weight proportionally distributed throughout all 4 chambers, but aside from this the presence of both transgenes rescues nmd-2J homozygotes to a wild-type phenotype including no cardiomyopathy
