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]

The c.1580C>T (p.S527L) alteration is located in exon 4 (coding exon 4) of the KLHL21 gene. This alteration results from a C to T substitution at nucleotide position 1580, causing the serine (S) at amino acid position 527 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
