Ambry Genetics

Sep 26, 2023

The c.823G>A (p.V275I) alteration is located in exon 1 (coding exon 1) of the MPPED1 gene. This alteration results from a G to A substitution at nucleotide position 823, causing the valine (V) at amino acid position 275 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
