Ambry Genetics

Apr 27, 2023

The c.1081G>T (p.V361L) alteration is located in exon 5 (coding exon 4) of the KLHL8 gene. This alteration results from a G to T substitution at nucleotide position 1081, causing the valine (V) at amino acid position 361 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
