Ambry Genetics

Apr 20, 2024

The c.1140G>T (p.M380I) alteration is located in exon 5 (coding exon 5) of the KLHL1 gene. This alteration results from a G to T substitution at nucleotide position 1140, causing the methionine (M) at amino acid position 380 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
