Ambry Genetics

Sep 15, 2021

The c.1498C>A (p.L500M) alteration is located in exon 4 (coding exon 3) of the KLHL33 gene. This alteration results from a C to A substitution at nucleotide position 1498, causing the leucine (L) at amino acid position 500 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
