Ambry Genetics

Oct 27, 2022

The c.469C>T (p.R157C) alteration is located in exon 1 (coding exon 1) of the TEKT4 gene. This alteration results from a C to T substitution at nucleotide position 469, causing the arginine (R) at amino acid position 157 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
