Genes affected

KLHL20 (HGNC:25056): (kelch like family member 20) The protein encoded by this gene is a member of the kelch family of proteins, which is characterized by a 44-56 amino acid repeat motif. The kelch motif appears in many different polypeptide contexts and contains multiple potential protein-protein contact sites. Members of this family are present both throughout the cell and extracellularly, with diverse activities. [provided by RefSeq, Jul 2008]

The c.1242T>G (p.F414L) alteration is located in exon 8 (coding exon 7) of the KLHL20 gene. This alteration results from a T to G substitution at nucleotide position 1242, causing the phenylalanine (F) at amino acid position 414 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
