Genes affected
WNK1 (HGNC:14540): (WNK lysine deficient protein kinase 1) This gene encodes a member of the WNK subfamily of serine/threonine protein kinases. The encoded protein may be a key regulator of blood pressure by controlling the transport of sodium and chloride ions. Mutations in this gene have been associated with pseudohypoaldosteronism type II and hereditary sensory neuropathy type II. Alternatively spliced transcript variants encoding different isoforms have been described but the full-length nature of all of them has yet to be determined.[provided by RefSeq, May 2010]

The WNK1 c.1834G>A; p.Gly612Ser variant (rs146450828), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 310740). This variant is found in the Latino population with an allele frequency of 0.079% (28 /35420 alleles) in the Genome Aggregation Database. The glycine at codon 612 is moderately conserved, and computational analyses predict that this variant is neutral (REVEL: 0.086). Due to limited information, the clinical significance of the p.Gly612Ser variant is uncertain at this time. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1834G>A (p.G612S) alteration is located in exon 7 (coding exon 7) of the WNK1 gene. This alteration results from a G to A substitution at nucleotide position 1834, causing the glycine (G) at amino acid position 612 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Illumina Laboratory Services, Illumina
Significance:Benign
Review Status:criteria provided, single submitter
Collection Method: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. -
