OMIM: 177735
Orphanet: ORPHA171871

Targets

Mineralocorticoid receptor
Role:  A mild form of mineralocorticoid resistance involving only one allele. This is distinct from the severe autosomal recessive form of PHA1 which involves mutations in the epithelial sodium channel genes. Recent studies have addressed the broader consequences of haploinsufficiency that characterises PHA1 with MR mutations for the pituitary adrenal axis (Walker et al. 2014) and for the cardiovascular system (Escoubet et al., 2013).
Comments:  Alteration at the receptor level: G633R, Q776R, L924P and L979P mutants lose activity.
