Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 1P and 4B. PP2 BP4_Strong

The NM_213655.5(WNK1):c.5273G>A(p.Cys1758Tyr) variant causes a missense change involving the alteration of a non-conserved nucleotide. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C1758S) has been classified as Benign.

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]

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PP2: Missense variant where missense usually causes diseases, WNK1
• BP4: Computational evidence support a benign effect (MetaRNN=0.06281781).
