Ambry Genetics

Feb 28, 2024

The c.2206C>T (p.R736C) alteration is located in exon 18 (coding exon 17) of the FAM65C gene. This alteration results from a C to T substitution at nucleotide position 2206, causing the arginine (R) at amino acid position 736 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
