MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Nonvoltage-gated, amiloride-sensitive, sodium channels control fluid and electrolyte transport across epithelia in many organs. These channels are heteromeric complexes consisting of 3 subunits: alpha, beta, and gamma. This gene encodes the alpha subunit, and mutations in this gene have been associated with pseudohypoaldosteronism type 1 (PHA1), a rare salt wasting disease resulting from target organ unresponsiveness to mineralocorticoids. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Apr 2009]
PHENOTYPE: Homozygotes for targeted null mutations exhibit skin with epithelial hyperplasia, abnormal nuclei, premature lipid secretion, and abnormal keratohyaline granules. Mutants die within 40 hours of birth due to inability to clear their lungs of liquid. [provided by MGI curators]
