Ambry Genetics

Oct 17, 2023

The c.1517C>T (p.T506I) alteration is located in exon 4 (coding exon 4) of the KBTBD4 gene. This alteration results from a C to T substitution at nucleotide position 1517, causing the threonine (T) at amino acid position 506 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
