Genes affected

KLHL15 (HGNC:29347): (kelch like family member 15) This gene encodes a member of the kelch-like family of proteins that share a common domain structure consisting of an N-terminal broad-complex, tramtrack, bric-a-brac/poxvirus and zinc finger domain and C-terminal kelch repeat motifs. The encoded protein may be involved in protein ubiquitination and cytoskeletal organization. [provided by RefSeq, Apr 2009]

The c.1809C>G (p.C603W) alteration is located in exon 4 (coding exon 2) of the KLHL15 gene. This alteration results from a C to G substitution at nucleotide position 1809, causing the cysteine (C) at amino acid position 603 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
