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.

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 15, 2023 | The c.817G>A (p.A273T) alteration is located in exon 4 (coding exon 3) of the KLHL22 gene. This alteration results from a G to A substitution at nucleotide position 817, causing the alanine (A) at amino acid position 273 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
