Ambry Genetics

Feb 16, 2023

The c.352C>T (p.R118C) alteration is located in exon 4 (coding exon 4) of the PHF23 gene. This alteration results from a C to T substitution at nucleotide position 352, causing the arginine (R) at amino acid position 118 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
