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

Classification made for transcript

Verdict is Benign. Variant got -10 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), WNK1. . Gene score misZ 2.1626 (greater than the threshold 3.09). Trascript score misZ 4.652 (greater than threshold 3.09). GenCC has associacion of gene with neuropathy, hereditary sensory and autonomic, type 2A, hereditary sensory and autonomic neuropathy type 2, pseudohypoaldosteronism type 2C.

PP3

Multiple lines of computational evidence support a deleterious effect 7: AlphaMissense, BayesDel_noAF, Cadd, FATHMM_MKL, phyloP100way_vertebrate, PrimateAI, PROVEAN [when BayesDel_addAF, max_spliceai, MetaRNN, MutationAssessor, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.01610139).

BP6

Variant 12-754242-A-T is Benign according to our data. Variant chr12-754242-A-T is described in ClinVar as [Likely_benign]. Clinvar id is 538536.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Oct 01, 2019

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
