Genes affected

KLHL6 (HGNC:18653): (kelch like family member 6) This gene encodes a member of the kelch-like (KLHL) family of proteins, which is involved in B-lymphocyte antigen receptor signaling and germinal-center B-cell maturation. The encoded protein contains an N-terminal broad-complex, tramtrack and bric a brac (BTB) domain that facilitates protein binding and dimerization, a BTB and C-terminal kelch (BACK) domain, and six C-terminal kelch repeat domains. Naturally occurring mutations in this gene are associated with chronic lymphocytic leukemia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2017]

Nov 22, 2024

The c.965T>C (p.M322T) alteration is located in exon 4 (coding exon 4) of the KLHL6 gene. This alteration results from a T to C substitution at nucleotide position 965, causing the methionine (M) at amino acid position 322 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
