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 p.Q1101* pathogenic mutation (also known as c.3301C>T), located in coding exon 10 of the WNK1 gene, results from a C to T substitution at nucleotide position 3301. This changes the amino acid from a glutamine to a stop codon within coding exon 10. This alteration was detected in the homozygous state in an individual with hereditary sensory and autonomic neuropathy type II; however, clinical details were limited (Lafreniere RG et al. Am J Hum Genet, 2004 May;74:1064-73). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Gln1101*) 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). This variant is present in population databases (rs111033590, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with hereditary sensory and autonomic neuropathy (PMID: 15060842). This variant is also known as c.943C>T (p.Gln315*). ClinVar contains an entry for this variant (Variation ID: 5166). For these reasons, this variant has been classified as Pathogenic. -
