Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2022The c.2348C>G (p.A783G) alteration is located in exon 11 (coding exon 11) of the PSD3 gene. This alteration results from a C to G substitution at nucleotide position 2348, causing the alanine (A) at amino acid position 783 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
