Genes affected

KLHL22 (HGNC:25888): (kelch like family member 22) Enables 14-3-3 protein binding activity. Involved in several processes, including cellular protein metabolic process; cellular response to leucine; and mitotic spindle assembly checkpoint signaling. Located in several cellular components, including cytosol; intercellular bridge; and microtubule cytoskeleton. Part of Cul3-RING ubiquitin ligase complex. Colocalizes with lysosome and nucleus.

Ambry Genetics

Feb 01, 2023

The c.1231A>G (p.N411D) alteration is located in exon 5 (coding exon 4) of the KLHL22 gene. This alteration results from a A to G substitution at nucleotide position 1231, causing the asparagine (N) at amino acid position 411 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
