Variant summary

Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM2PM5PP3PP5_Moderate

The NM_000336.3(SCNN1B):​c.1847C>T​(p.Pro616Leu) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,460,044 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P616S) has been classified as Likely pathogenic.

Genes affected
SCNN1B (HGNC:10600): (sodium channel epithelial 1 subunit beta) 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]
