Ambry Genetics

Nov 15, 2021

The c.2752C>T (p.R918W) alteration is located in exon 22 (coding exon 21) of the FAM65C gene. This alteration results from a C to T substitution at nucleotide position 2752, causing the arginine (R) at amino acid position 918 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
