Ambry Genetics

Mar 29, 2022

The c.1042C>T (p.R348W) alteration is located in exon 6 (coding exon 5) of the ZSCAN20 gene. This alteration results from a C to T substitution at nucleotide position 1042, causing the arginine (R) at amino acid position 348 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
