Genes affected

KCNJ5 (HGNC:6266): (potassium inwardly rectifying channel subfamily J member 5) This gene encodes an integral membrane protein which belongs to one of seven subfamilies of inward-rectifier potassium channel proteins called potassium channel subfamily J. The encoded protein is a subunit of the potassium channel which is homotetrameric. It is controlled by G-proteins and has a greater tendency to allow potassium to flow into a cell rather than out of a cell. Naturally occurring mutations in this gene are associated with aldosterone-producing adenomas. [provided by RefSeq, Aug 2017]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM1: In a topological_domain Cytoplasmic (size 233) in uniprot entity KCNJ5_HUMAN there are 5 pathogenic changes around while only 1 benign (83%) in NM_000890.5
• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 11-128912116-CC-TG is Benign according to our data. Variant chr11-128912116-CC-TG is described in ClinVar as [Likely_benign]. Clinvar id is 412766.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

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. -
