Ambry Genetics

Dec 10, 2024

The c.755A>G (p.Y252C) alteration is located in exon 6 (coding exon 6) of the USP39 gene. This alteration results from a A to G substitution at nucleotide position 755, causing the tyrosine (Y) at amino acid position 252 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
