Genes affected

KLHL17 (HGNC:24023): (kelch like family member 17) The protein encoded by this gene is expressed in neurons of most regions of the brain. It contains an N-terminal BTB domain, which mediates dimerization of the protein, and a C-terminal Kelch domain, which mediates binding to F-actin. This protein may play a key role in the regulation of actin-based neuronal function. [provided by RefSeq, Aug 2010]

Ambry Genetics

May 10, 2024

The c.457G>T (p.A153S) alteration is located in exon 3 (coding exon 3) of the KLHL17 gene. This alteration results from a G to T substitution at nucleotide position 457, causing the alanine (A) at amino acid position 153 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
