Ambry Genetics

Dec 23, 2022

The c.13G>A (p.G5S) alteration is located in exon 1 (coding exon 1) of the MPV17L2 gene. This alteration results from a G to A substitution at nucleotide position 13, causing the glycine (G) at amino acid position 5 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
