RCV000281301 | SCV000381966 | benign | Pseudohypoaldosteronism type 2C | 2018-01-13 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. |
| Invitae | RCV001240672 | SCV001413640 | uncertain significance | Neuropathy, hereditary sensory and autonomic, type 2A; Pseudohypoaldosteronism type 2C | 2023-06-28 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt WNK1 protein function. ClinVar contains an entry for this variant (Variation ID: 310825). This variant has not been reported in the literature in individuals affected with WNK1-related conditions. This variant is present in population databases (rs143361850, gnomAD 0.009%). This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 1552 of the WNK1 protein (p.Ser1552Phe). |
| Ambry Genetics | RCV002338889 | SCV002636825 | uncertain significance | Inborn genetic diseases | 2022-01-31 | criteria provided, single submitter | clinical testing | The p.S1552F variant (also known as c.4655C>T), located in coding exon 19 of the WNK1 gene, results from a C to T substitution at nucleotide position 4655. The serine at codon 1552 is replaced by phenylalanine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
