Ambry Genetics

Jul 27, 2021

The c.1372G>T (p.V458L) alteration is located in exon 4 (coding exon 4) of the KBTBD4 gene. This alteration results from a G to T substitution at nucleotide position 1372, causing the valine (V) at amino acid position 458 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
