Genes affected

KLHL21 (HGNC:29041): (kelch like family member 21) Enables cullin family protein binding activity. Contributes to ubiquitin-protein transferase activity. Involved in chromosome passenger complex localization to spindle midzone; protein ubiquitination; and regulation of cytokinesis. Located in polar microtubule. Part of Cul3-RING ubiquitin ligase complex. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Jul 26, 2021

The c.1712G>A (p.R571H) alteration is located in exon 4 (coding exon 4) of the KLHL21 gene. This alteration results from a G to A substitution at nucleotide position 1712, causing the arginine (R) at amino acid position 571 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
