Ambry Genetics

Mar 07, 2023

The c.1153C>T (p.R385W) alteration is located in exon 10 (coding exon 10) of the ZCCHC4 gene. This alteration results from a C to T substitution at nucleotide position 1153, causing the arginine (R) at amino acid position 385 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
