Ambry Genetics

Aug 17, 2021

The c.1882T>A (p.F628I) alteration is located in exon 15 (coding exon 13) of the GTF3C2 gene. This alteration results from a T to A substitution at nucleotide position 1882, causing the phenylalanine (F) at amino acid position 628 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
