Ambry Genetics

Aug 12, 2021

The c.1206G>T (p.E402D) 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 1206, causing the glutamic acid (E) at amino acid position 402 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
