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 beta subunit, and mutations in this gene have been associated with pseudohypoaldosteronism type 1 (PHA1), and Liddle syndrome. [provided by RefSeq, Apr 2009]
PHENOTYPE: Homozygous mutation of this gene results in death shortly after birth, decreased serum sodium levels but higher urine sodium levels and increased serum potassium and chloride levels but lower potassium urine levels. Another homozygous mutation exhibits no abnormal phenotype. [provided by MGI curators]
