• Background Sensitivity: mice on a congenic BALB/c background die prematurely after developing adult-onset neuromuscular degeneration, similar to that of nmf375 homoyzygotes on the BALB/c background, but do live to at least 7 month of age unlike homozygotes on a C57BL/6J background which die at or before birth.
