Ambry Genetics

Oct 10, 2023

The c.655C>T (p.R219C) alteration is located in exon 2 (coding exon 2) of the KLF16 gene. This alteration results from a C to T substitution at nucleotide position 655, causing the arginine (R) at amino acid position 219 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
