Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2022The c.2794C>A (p.L932M) alteration is located in exon 15 (coding exon 15) of the PSD3 gene. This alteration results from a C to A substitution at nucleotide position 2794, causing the leucine (L) at amino acid position 932 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
