Comment on mode of inheritance: Only one report of biallelic mutations, and in that case there were 3 in the patient, and were reported to occur in healthy populationsCreated: 5 Sep 2019, 4:24 p.m. | Last Modified: 5 Sep 2019, 4:24 p.m.

Associated with Hypertension, early-onset, autosomal dominant, with exacerbation in pregnancy #605115 and Pseudohypoaldosteronism type I, autosomal dominant #177735 in OMIM.
The gene is also known as MCR.
Many cases of Pseudohypoaldosteronism associated with variants in NR3C2 reported in OMIM.
No inheritance pattern listed in OMIM. However, most reports are for monoallelic inheritance (PMID: 9662404, 12788847, 16972228, 16954160). The only report of a biallelic case (PMID: 12483305 Arai et al 2003) was found in In a Japanese patient with sporadic PHA. 3 homozygous substitutions were found that had previously been reported to occur in healthy populations. The authors suggested that 2 or more 'functional' polymorphisms, any of which exhibits only slight effects on function alone and is incapable of causing PHA, may in the right allelic combination induce the negative salt conservation characteristic of PHA.Created: 31 Aug 2019, 5:27 p.m. | Last Modified: 5 Sep 2019, 4:23 p.m.
