Ambry Genetics

Mar 02, 2023

The c.760A>G (p.T254A) alteration is located in exon 2 (coding exon 2) of the DPCR1 gene. This alteration results from a A to G substitution at nucleotide position 760, causing the threonine (T) at amino acid position 254 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
