Ambry Genetics

Nov 17, 2022

The c.521G>A (p.C174Y) alteration is located in exon 3 (coding exon 3) of the CPPED1 gene. This alteration results from a G to A substitution at nucleotide position 521, causing the cysteine (C) at amino acid position 174 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
