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]

Sep 12, 2023

The c.375G>A (p.M125I) alteration is located in exon 3 (coding exon 3) of the KLHL17 gene. This alteration results from a G to A substitution at nucleotide position 375, causing the methionine (M) at amino acid position 125 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
