Genes affected

KLHL40 (HGNC:30372): (kelch like family member 40) This gene encodes a protein containing a BACK domain, a BTB/POZ domain, and 5 Kelch repeats, however, its exact function is not known. The gene and the multi-domain protein structure are conserved across different taxa, including primates, rodents, chicken and zebrafish. [provided by RefSeq, Dec 2012]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant (GRCh38; NM_152393.4:c.1762G>A:p.Glu588Lys) results in a missense mutation with the conversion of Glutamate (Acidic amino acid) to Lysine (Basic amino acid) in the KLHL40 protein. This variant has a strong Conservation score. Multiple lines of computational evidence support a deleterious effect on the gene or gene product for this variant. Reputable source recently reports variant as benign. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. This variant is associated with the following publications: PubMed: 20301465, 23746549, 27528495, 26754003, 27762439. Based on conflicting evidence or insufficient data to determine whether the variant is benign or pathogenic, the clinical significance of this alteration remains unclear. In summary, this variant meets our criteria for classification as of Unknown Clinical Significance based on the evidence outlined. -
