Ambry Genetics

Nov 27, 2023

The c.617A>G (p.Y206C) alteration is located in exon 5 (coding exon 5) of the CCDC42 gene. This alteration results from a A to G substitution at nucleotide position 617, causing the tyrosine (Y) at amino acid position 206 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
