Ambry Genetics

Apr 24, 2024

The c.346G>T (p.A116S) alteration is located in exon 1 (coding exon 1) of the PM20D2 gene. This alteration results from a G to T substitution at nucleotide position 346, causing the alanine (A) at amino acid position 116 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
