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]

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jul 17, 2023	This variant is present in population databases (rs111033591, gnomAD 0.008%). This premature translational stop signal has been observed in individual(s) with autosomal recessive hereditary sensory and autonomic neuropathy (PMID: 15911806). ClinVar contains an entry for this variant (Variation ID: 5168). For these reasons, this variant has been classified as Pathogenic. This sequence change creates a premature translational stop signal (p.Arg1076*) in the WNK1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in WNK1 are known to be pathogenic (PMID: 22910560). -
