Ambry Genetics

Jan 05, 2022

The c.1942G>A (p.V648I) alteration is located in exon 15 (coding exon 15) of the STRN3 gene. This alteration results from a G to A substitution at nucleotide position 1942, causing the valine (V) at amino acid position 648 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
