Ambry Genetics

Sep 14, 2022

The c.43C>T (p.R15C) alteration is located in exon 2 (coding exon 1) of the ZNF646 gene. This alteration results from a C to T substitution at nucleotide position 43, causing the arginine (R) at amino acid position 15 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
