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.708G>T (p.M236I) alteration is located in exon 4 (coding exon 3) of the KLHL20 gene. This alteration results from a G to T substitution at nucleotide position 708, causing the methionine (M) at amino acid position 236 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
