not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 27, 2022The c.401G>A (p.R134Q) alteration is located in exon 3 (coding exon 2) of the PSD2 gene. This alteration results from a G to A substitution at nucleotide position 401, causing the arginine (R) at amino acid position 134 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
