Key result
Complete absence of NPRA in mice causes hypertension, cardiac hypertrophy, and sudden death before 6 months of age in 100% of males (15/15) and 6.25% of females (1/16).

Does the absence of NPRA cause hypertension, cardiac hypertrophy, and sudden death in mice?
Complete absence of NPRA in mice causes systemic hypertension, cardiac hypertrophy, and lethal vascular events, particularly in males, resembling untreated human hypertensive heart disease.
Reddick et al. (2020) studied Hypertension and cardiac hypertrophy (n=31). Lack of functional Npr1 gene (NPRA deficiency) was evaluated on Sudden death. Complete absence of NPRA in mice causes hypertension, cardiac hypertrophy, and sudden death before 6 months of age in 100% of males (15/15) and 6.25% of females (1/16).
