Ambry Genetics

Dec 23, 2022

The c.634G>A (p.V212I) alteration is located in exon 5 (coding exon 5) of the PSMG1 gene. This alteration results from a G to A substitution at nucleotide position 634, causing the valine (V) at amino acid position 212 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
