Genes affected
KLHL3 (HGNC:6354): (kelch like family member 3) This gene is ubiquitously expressed and encodes a full-length protein which has an N-terminal BTB domain followed by a BACK domain and six kelch-like repeats in the C-terminus. These kelch-like repeats promote substrate ubiquitination of bound proteins via interaction of the BTB domain with the CUL3 (cullin 3) component of a cullin-RING E3 ubiquitin ligase (CRL) complex. Muatations in this gene cause pseudohypoaldosteronism type IID (PHA2D); a rare Mendelian syndrome featuring hypertension, hyperkalaemia and metabolic acidosis. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Mar 2012]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 7 ACMG points.

PM1
In a hotspot region, there are 5 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 2 uncertain in NM_017415.3
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the KLHL3 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 22 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 2.9931 (below the threshold of 3.09). Trascript score misZ: 3.5661 (above the threshold of 3.09). GenCC associations: The gene is linked to pseudohypoaldosteronism type 2D.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.8
PP5
Variant 5-137637338-G-A is Pathogenic according to our data. Variant chr5-137637338-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 31546.Status of the report is no_assertion_criteria_provided, 0 stars.
