Ambry Genetics

Dec 27, 2023

The c.1473G>A (p.M491I) alteration is located in exon 7 (coding exon 7) of the KLHL1 gene. This alteration results from a G to A substitution at nucleotide position 1473, causing the methionine (M) at amino acid position 491 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
