Ambry Genetics

Feb 01, 2023

The c.790C>T (p.R264C) alteration is located in exon 4 (coding exon 4) of the FRZB gene. This alteration results from a C to T substitution at nucleotide position 790, causing the arginine (R) at amino acid position 264 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
