Genes affected
SCNN1G (HGNC:10602): (sodium channel epithelial 1 subunit gamma) 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 gamma subunit, and mutations in this gene have been associated with Liddle syndrome.

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

p.Gly183Ser in exon 3 of SCNN1G: This variant is not expected to have clinical s ignificance because it has been identified in 3.6% (868/24032) of African chromo somes including 17 homozygotes by the Genome Aggregation Database (gnomAD, http: //gnomad.broadinstitute.org; dbSNP rs5736) and there is lack of conservation acr oss species, including mammals. Of note, 44 species have a serine (Ser) residue at this position despite high nearby amino acid conservation. ACMG/AMP Criteria applied: BA1, BS4, BP4. -

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
