Ambry Genetics

Oct 16, 2023

The c.2823G>T (p.Q941H) alteration is located in exon 15 (coding exon 15) of the PSD3 gene. This alteration results from a G to T substitution at nucleotide position 2823, causing the glutamine (Q) at amino acid position 941 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
